Just finished my new build:

- Ryzen 7 9800X3D

- ASUS TUF B850 Gaming

- 64GB DDR5 6000 CL30

- RTX 4070 Ti

Honestly, I expected a bigger jump in MSFS 2024 performance.

Even with this setup, I still struggle at heavy airports like iniBuilds EGLL using the iniBuilds A350, and that’s without AI traffic. FPS can initially look good, but they progressively drop during the session, especially on the ground. Once I add AI traffic, things become much worse.

I mostly fly in 4K (sony TV 43”) and I’m starting to think the oldest/weaker part of the system now is probably the RTX 4070 Ti.

I’m considering upgrading to an RTX 5080.

For those already using one in MSFS 2024, especially with demanding aircraft/sceneries, did you notice a significant improvement in:

- ground performance,

- VRAM usage,

- frame consistency,

- long-flight FPS degradation?

Would love to hear your experiences before making the jump.

Thanks!

Have you tried lowering graphic your settings?

Have you tried lowering graphic your settings?

Yes, i do have most of them in LOW some medium oviolsuy no ai traffic, shadows…

My MSFS system is similar to yours, except I run an RTX 4090 (24GB VRAM). I run at a ~26% lower resolution (3840x1600) than 4K, and have no issues holding a smooth 40 fps native (80 with frame generation) with heavy acft and scenery add-ons in FS 2024. So I surmise that video system performance explains the difference between our experiences running MSFS 2024.

I think your 4070Ti GPU probably does present a significant bottleneck given that you're driving a high-bandwidth 4K (8.3 Mpx/frame) display. Non-flightsim game benches rate the 5080 anywhere from 15% to 45% faster, but I'd suspect that having 33% more VRAM on the 5080 (16GB vs 12GB) also makes a significant difference in MSFS at 4K.

The 5090 is king, followed by the 5080 and 4090. A used 4090 is a golden deal because native frames always look better and cleaner than AI-generated ones. While the 5080 uses Frame Gen to keep up for image quality.

The 5070 Ti might show high FPS, and very good on all games except in MSFS, the AI often causes image artifacts and looks unnatural.

Worth considering a Radeon RX 9070 XT too, slightly cheaper than a xx90 .. good bang for buck.

Honestly, AMD beats NVIDIA in FPS numbers. you got like 120+ FPS for most time, but the overall image quality looks almost cartoonish in comparison.

In the end, your monitor is only as good as your GPU.

ur money and ur GPU 😄

I don't know if SU5 will be enough to use the 5080 on a 4K monitor.

I haven't found a good review of the 5080 and its VRAM usage in MSFS.

Just my two cents.... have you actually figured out what your limiting factor is? I would assume you limiting factor is the GPU... Are you e.g. getting a VRAM message in-sim? A 16GB GPU for a 4K application is alright on paper - but especially in MSFS2024, VRAM is heavily utilized with additional stuff. Have you actually tried to run it on a smaller resolution monitor?

You could get more VRAM - a 24 or 32GB VRAM GPU would be nice but is really expensive. A "relatively" cheap option would be a AMD 7900XTX with 24GB VRAM. These were released in 2022 - so maybe you can get one used for a good price and sell your 4070Ti to limit any additional costs... The 7900XTX is actually competing with a 4080 in pure rasterization - so it is not a bad choice for a GPU at all.

But - First thing I would recommend to try to improve your situation - using the render scaling option in the graphic settings - basically telling your GPU your monitor has a smaller resolution and then scaling it up to your 4K. You could start moving down in 10% increments like 90%, 80%,... to see if you are seeing improvements. Maybe limiting you frame rate with 2x frame generation - maybe 30/60 - or 15/30 - nothing to wild... Check you usual subjects in a VRAM limited scenario (TLOD, OLOD, Texture resolution, clouds, reytraced shadows...). I actually started on a LOW preset, working my way up with must have and nice to have graphic settings. Some of these settings seems to require e restart (e.g. texture resolution)....

Try closing anything you might have open on the side on your PC. (big VRAM users are Volanta, web-browsers, PDF / office software (maybe a checklist open?))...

As for your struggle with heavy inibuilds airports - there is a lot of objects the sim has to keep "in mind" (VRAM) so these are not just popping in when changing your view.... logically having individual chairs in terminal buildings is not helping here. I personally gave up on buying bigger detailed airports, especially if they have detailed interior. For me personally - for me it's just not worth compromising the flying experience. Maybe it is alright using a bush-plane - but a lot of people are having issues with more complex airliners and AI traffic. But then again, sometimes i think MSFS was not programmed with airliner operation in mind considering the quality of ATC, weather depiction or the handling of complex sceneries.

And the last thought ... I've never checked / monitored my VRAM usage in 2020 - ever. I have the feeling that a 16GB GPU in MSFS2024 is a general limitation and needs tinkering to find a good setting. Don't know if that is a feature or a bug - so there is a chance that everything will be just peachy with SU6... and then again gone with SU7 - one never knows. I've personally got MSFS2024 after SU5 - but I've followed the discussions since release.
