Assuming @Sunday748 is GPU limited in the first place. Otherwise FSR isn’t going to help.

Btw - I just tried the Adrenalin video recording and screen shot features in v24.1.1 and was impressed with how much AMD has improved video recording. The screen shots however are still washed out in 4k HDR (my default screen mode). The video recordings I did at 90fps/default video bitrate of 30mbps were pretty good and only impacted my fps by about 5% but when you’ve doubled your fps with frame gen I notice very few artifacts.
Thanks for the advise but I´m still on windows 10 but I have vrr on but it still doesn´t work… Hopefully msfs will update the game so you can play with fullscreen or amd update their afmf to work with borderless fullscreen in the future
Is FSR any good over TAA with down-sampling? I was tempted to switch over even though my 6600m has 8G VRAM. I currently limit it to 30fps to avoid fluctuations.

Yes, I run FSR2 at the quality setting all the time and it should not have an impact on VRAM. Your mileage may vary but by all means try it.

AMD has provided guidance on when FSR2 is acceptable to use, and it’s resolution based.
In my case, that chart was spot on. My 6600XT can run it at 1440p fine. If I try FSR2 at my native 4k, it takes the nominal 25-30fps and tanks it into the low teens with VRAM overrun. The sim’s FPS display doesn’t just turn red, but goes into purple! Lol. And the only way to get performance back is to turn FSR2 off, then completely close and restart the sim. @Aleo5069 having a 6600m mobile GPU would presumably be even worse and require a lower native resolution.
And while yes FSR2 helps with my frame rates at 1440p, I’ve found it looks better at native 1440p (which my monitor upscales/stretches great) and I just tune my other settings down to compensate for 60fps in most situations, including using TAA. FSR2 causes text to be too blurry.

Yes, great point. I am currently running MSFS at native 4K on my 28" screen. I need to use TAA at 80% scale to maintain stable 30fps, while anything below 80% makes digital screens hard to read. I’ll try lowering it to 1440p and see if FSR2 helps, shall I change that in game or in Windows settings?
I use to run 4k resolution rendered at around 75-80% in the sim’s settings, and I think the change to 1440p rendered at 100% scaling provides a sharper image. These are all sim settings, and left the Windows settings alone.
If you aren’t satisfied with the frame rates at that point, I would suggest bringing up the sim’s built in FPS monitor to see where the bottleneck is (main thread or GPU limited), and adjust your sim settings accordingly.

I tried multiple settings and figured that at 3K (3072*1728) I could get pretty nice imagery with FSR quality while keeping ~40fps. I noticed from Gamebar that neither CPU nor GPU nor VRAM is exceeding 80% so I’ll try to investigate more on that. Thanks for your help and suggestions!

This is why I mentioned using the sim’s FPS monitor. The sim will hammer only one or two cores, which leads to inaccurate results from other stat monitors that only look at total CPU utilization. In other words, if only one core is running full tilt for the sim, then you are CPU bottlenecked even though the other cores are at low utilization. The sim’s FPS monitor will accurately tell you if it’s the CPU limiting you, and I suspect it is if the GPU is not running at near full utilization.
If you’re not sure where to find it, turn on developer mode in the sim settings to get the toolbar at the top. You’ll find the FPS display in the debug pulldown menu.

If I may ask, do you mean that you are not seeing a noticeable increase in VRAM usage when enabling FSR 2? For me and a few others it adds a huge VRAM overhead that ends up tanking the frame rate, but Asobo can’t reproduce it, so I’m wondering if there is any way this bug can be avoided.

Did you see the screenshot in my reply a few posts up showing the recommended cards and resolutions for FSR? From my understanding, it’s not a bug, but a limitation of FSR and nothing Microsoft or Asobo can do about it. It would be something AMD would have to address, assuming that’s even possible.
In other games I’m using FSR 2/3 just fine with no additional VRAM overhead to be seen. The fact that it persists even when reverting back to TAA (or disabling anti-aliasing for that matter) makes me fairly sure that it is a bug, which could be either down to Asobo’s implementation or AMD’s drivers. I’m trying to find out why Asobo and some people are seemingly not getting this bug.
Fair enough. The sim is the only time I’ve considered FSR and my other games are just fine without, so I hadn’t seen that discrepancy. I’m just going off my own experience and the AMD recommendations. I personally prefer reducing settings over scaling and frame generation anyway, so bug or not, I’m not bothered by it.
So I did some testing with the sim with regards to VRAM usage on my PC (RX 7900 XTX - see additional details in my profile). The approach I used to minimize any impacts on VRAM for each anti-aliasing type is as follows:
- Loaded up the sim with the base settings below
- Spawned onto KJFK runway 31L with stock Cessna 172
- Waited for a minute or so for things to settle down then noted VRAM used
- Press Exit->General Options->Graphics & change AA setting then Apply Settings->Go Back
- I would then press Resume to return onto the runway at KJFK
- Back to 3 to note VRAM used
So the VRAM used for each AA type is as follows:
- AA off - 17.7Gig
- TAA - 17.8Gig
- FSR2 Quality - 17.4Gig
- FSR2 Balanced - 16.7Gig
- FSR2 Performance - 16.3Gig
- FSR2 Ultra Performance - 15.5Gig
Please note: I cycled around to note each AA type 3-4 times and then cycled around in a random fashion a couple more times to check accuracy. The values above were very consistent for each AA setting. Also, my gpu is AMD based with 24Gig of VRAM - your mileage may vary depending upon your HW/SW

Thank you for the detailed tests! Your results mirror what users with 24GB cards (usually the RTX 3090/4090) report in regard to MSFS being able to allocate 16GB or more VRAM in DX12.
I’m now having the suspicion that toggling FSR 2 breaks the memory allocation system, which would cause the VRAM budget on 8-10GB cards to be exceeded very easily, and would explain Asobo not being able to reproduce this if they are testing on high-end cards only. Hopefully something they can fix when updating to FSR 3…

I have an incredible increase in FPS with AMD Fluid Motion Frames, sometimes up to 200%!!!
For anyone who hasn’t turned it on yet, you should definitely do so, the gain in FPS is incredible
I normally had it turned off but have found that the impact on Microsoft Flight Simulator is really fantastic

Yes, it does an awesome job.

The sweet spot is if you’re getting ~50-60fps and have at least a 120Hz monitor/TV with freesync. Many people still don’t realize it’s available - just turn it on once in the driver and you’re good to go!
I now usually achieve 100 to 120 FPS in helo flight… Even in downtown Manhattan it’s still 90 to 100 FPS at Ultra settings… The fluid on my 75 hz monitor is simply incredible to look at… In the end you only ever see the frequency of the monitor and everything below it can be perceived as blur or flickering… 120 hz I can’t judge. Maybe someone here has one and can tell us their impressions between a high and a low frame rate… For the reasons you mentioned, I would avoid such high-frequency monitors
