Improved FPS in MSFS | DLSS 3 - Fact or Fake? | Tested with the RTX 4090

dlss3 the new super sampling an upscaling application from Nvidia which has just been introduced has certainly gained its fair share of detractors and Skeptics in this video I put it to the test in Microsoft flight simulator to establish fact from fiction welcome to the Sim Hangar my name's Mark thanks for watching and let's get started while the hairs were running almost as soon as the RTX 1490 was released and is often the case people are all too quick to put a negative spin on things numerous channels have released videos on it my personal opinion the most notable being Hardware unboxed but don't get me wrong this is an excellent video and a recommended watch Link in the notes Below in that video they highlighted the strengths and weaknesses of DLS S3 the main issue potentially being the difference between an increase in fps but an increase in latency as well meaning you could get your FPS counter reading 60 frames per minute but in game it feels like 30 frames so despite an improved FPS you're getting less response now I believe this is an accurate statement for first-person shooters or any fast-paced game but is far less of an issue for something like a flight simulation where all movement is comparatively slower and the hardware unbox video mentioned this numerous times as well as DLS S3 being ideal for predominantly single core applications and Microsoft flight simulator certainly fits into that category it's still very early days for DLS S3 and further optimizations are to come and in this video I'd put it to the test we're not going to get bogged down into the details of how DLS S3 works but normally an increase in fps means a reduction in latency that's the time between frames this anomaly occurs because DLS S3 does the same upscaling rendering as DLS S2 as shown in frame 1 and frame 3 above but then the GPU will independently insert an additional frame frames two and four this is a transitional frame it's not interlacing and that additional frame will provide full smoother gameplay creating additional frame even though independent of the CPU does take time and thus the potential increase in latency there's no in inserted frames or AI generated using the graphic card's tensor cores they aren't all intents and purposes and estimation accounting for movement and Shadow and so on of a transitional frame between a traditional first and second frame this new process then may well be more prone to artifacts within the displayed image and the faster the movement the more noticeable these potentially could be so with all that in mind the question is what impact will this have in Microsoft flight simulator Let's test it out here's a quick summary of the test conditions CPU is a 99 10 900k 32 gigabytes of RAM and the Asus tough gaming RTX 1490 game mode is off but Hardware accelerated GPU scheduling is on as this is required for DLS S3 as is dx12 beta in Sim my Nvidia control panel settings are all standard except for power management mode and texture filtering quality are both set to high performance generally speaking the higher you push the resolution on DLS S3 the better it performs my previous video was at 4K for this test I've decided to use my LG 2K monitor as arguably artifacts will be easier to recognize and my monitor is running at 144 Hertz just a quick note here the DLS S3 is no different to any other the screen display parameters the refresh rate of your monitor will determine the number of frames that can be displayed on screen the higher the refresh rate the better but for Microsoft flight simulator 144hz well that should be plenty if your monitor for example had a 60 hertz refresh rate or the maximum number of frames that could be displayed is 60. even if the frame counter reports higher you won't experience the impact of the higher frame rate to check or change the refresh rate of your monitor for those with Nvidia graphics cards go to the Nvidia control panel and select change resolution this is my LG monitor with a maximum resolution of 1440p I can choose various speeds 60 120 or 144 Hertz for me faster is better yes I want to keep those changes and we're done my version of Microsoft flight simulator is Sim update 11 beta deep learning super sampling 3 won't be generally available until official release in 11th of November to record performance I'm using msis afterburner video coming up on that shortly and I've selected a variety of information to be shown on screen for GPU we can see the temperature the speed that it's operating at and also importantly for 4090 owners how much wattage is being drawn let's have a quick look at my in Sim settings we'll start with TAA mode no dlss frame generation is off render scale 100 and Nvidia reflex is on all other settings are set at Ultra in Sim MSI afterburn is also showing the GPU memory usage and speed CPU temperature and you can see I'm running at five gigahertz how much RAM is being utilized and on the last line importantly is the current FPS and next to that is the latency we want to keep a closer eye on both latency and FPS latency is expressed in milliseconds 1000 milliseconds equals one second wherever Antwerp in Belgium and flying the F18 as we want something moving fast plus it has a heads up display hopefully making it easier to identify artifacts first test underway let me now enable the average frame counter there we are that's it on the right of the latency of number we'll keep our eye on the displays in the cockpit be flying relatively fast and relatively low and pass numerous wind turbines again should add us in identifying artifacts at the different settings in case you're wondering I'm using the Tobi tracker 5. the best head tracker in my personal opinion I've also got point of interests on so we can look at the markers and see if there's any artifacting there note I'm currently in TAA mode no dlss this test will be our Benchmark to measure against currently averaging 51 frames per second with an average latency I'd guess of around about 19 milliseconds displays look okay no evidence of any major artifacting we're now dropping in altitude or fly past the moving turbines they look okay to me but of course you must make your own determination overall the flight is felt very smooth and now at the end of our first test average FPS will take us 52 and I'd say the average latency was let's say about 19 milliseconds on to our second test we're going to stay on TAA but I'm going to turn on the Nvidia frame generation creation of extra frames Nvidia reflexes on by default reflex is designed to combat some of the latency all looking good let's go fly frame rates of laptop to newly double ground visuals look good but I am getting a little bit of flickering in the cockpit looks worse on the video than it did in the cockpit but it was evident currently averaging something in the region of about 10 milliseconds and about 98 FPS there is a slight drop in visual quality it's not significant but once again the flight feels very smooth I have noticed the latency seems more erratic with frame generation on in TAA mode some artifacting on that POI as we go past and that's the impact of the frame approximation the inserted frames but so far overall latency is better with frame generation on rather than with it off in TAA mode yes still a small flicker there something I'd prefer not to see but something I could live with not a major problem will now descend over this wind farm here to complete our test I'm paying particular attention to the moving vanes to see whether or not I'm getting any artifacting and I have to say nothing significant averaging 104 FPS and 10 milliseconds I can't identify any difference in the handling between frame generation on or off in TAA mode you would of course picked up that I was able to put on frame generation whilst in TAA and not dlss mode with a series 4000 Nvidia graphics card frame generation is available within different modes including TAA I think it's also valid to mention that the cockpit Clarity within TAA mode with frame generation on was not as bad as it may appear to you in the video but this is a result of me recording at 60 frames per second and the actual frame rate of the Sim being much higher please bear that in mind for test number three we're going to change to dlss mode but I'm going to turn frame generation off so effectively this is a dlss-2 test Nvidia reflex remains on okay here we go I'm just going to turn on the average frame counter on MSI afterburner there it is reminder this is effectively dlss2 mode all settings remain on Ultra immediate immediately obvious to me is the graphical anomalies within the cockpit they have all but disappeared and as mentioned earlier the responsiveness well there's no difference you're obviously only seeing a short extract of the flight but in each test I did throw the aircraft around a fair amount to test the responsiveness and once again we can note that the latency has increased compared to the frame generation on mode we can take an opportunity just to check out the clarity within the cockpit all is looking good nothing is blurry and as I mentioned in my earlier video the blurry cockpit seemed to have disappeared the HUD itself is very slightly fuzzy but it's like that in TVA mode as well so no significant difference there now coming in for our final flyover at the wind farm everything looking good to me and this flight will end with an average latency of about 19 milliseconds an average frame rate of about 50 FPS which is as expected pretty similar to the TAA mode with the 1490. our last test now coming up and of course it's dlss quality mode with frame generation on DLS S3 here we go let's start recording the average frames that's now up during the course of this test if you've checked the power draw you'll note it's nowhere near as high as often feared Clarity in the cockpit is much better than it was with TAA mode with frame generation on looks exactly as it did in dlss 2 mode I have to be honest the aircraft feels as responsive as ever and we are moving relatively quickly through the Sim at about 360 knots now turning to line up with the wind farms just want to check that point of Interest marker see if we've got any artifacting where have you gone there you are perhaps a tiny bit nothing significant and I have to say that my response times generally are being very good indeed and certainly within the 10 millisecond bracket well I have to say I've been impressed so far I'm gonna slow down a little bit and see whether or not that emphasizes any more artifacting the ground appears as clear as it did in dlss2 perhaps not quite as crisp as TAA mode but the difference is not massive now coming in for our final over the wind farm and again watching the veins to see if there's any artifacting don't know how this will come out on the video but looks okay to me perhaps a very slight jaggedness right on the edges but then again who's going to fly this close normally so we end on 101 frames per second an average of nine milliseconds so after all those tests what does it tell us first of all when looking at the results anything within two or three FPS should be considered more or less the same as each leg was flown individually and allowing for the vagrancies of each flight where frame generation was used reminder that's an extra frame latency was halved and so in effect the time between the first and second CPU calculated frame really didn't alter much at all which means the latency of using DLS S3 or frame Generations not a factor in this case it is perhaps also noteworthy that the TAA modes which don't include upscaling returned very similar if not exactly the same results as dlss and that is probably due to the grunt of the 4090 and at the end of the day when all is said and done DLS S3 is not really aimed at 1490 owners it's designed to boost performance for those that don't have enough GPU power perhaps those may be those ornate 40 70 or 40 60 or maybe even or 40 50 if they ever come to pass and perhaps also RTX 3000 owners if and when DLS S3 is made available to them a series 3000 cards also have their Optical flow generator and on less powerful graphic card then artifacting and latency May well become a bigger Factor than I've indicated in these results but perhaps what it does indicate is that dlss-3 does have great potential for the future and enable flight simmers to get a smooth performance where otherwise they wouldn't be able to do so or perhaps up their settings time will tell but with DLS S3 it's not just about your graphics card it's about your CPU and your memory and these factors are going to play a much bigger part in the future in Flight simming I hope you found this useful and informative thanks for joining me today and thanks for watching see you soon and bye for now
