I’m frustrated and don’t know what to do and hope to get some advice and opinions for my problem.
I’ve played MSFS 2020 with my HP Reverb G2 on high settings at ~35-40 FPS in the past and was quite happy with it.
My system is running with an i9-10850k @ 5.0 GHz, RTX 3080 10GB and 32 GB RAM.
Now I’ve upgraded to MSFS 2024, a Pimax Crystal Light and Windows 11 and it’s a disaster.
I’ve overridden the headset resolution to 3500x4142 with the OpenXR toolkit, run DLSS Quality and the low preset and only get ~15-20 FPS on the ground at KTVL.
Why are the FPS so much worse now and the sim is unplayable?
I’m thinking about upgrading to an RTX 5080, or is this bottlenecking the CPU?
It sounds like you may have to re-configure your settings to discover whether it is a 2024 issue or whether you are just expecting too much. You don’t say whether you are using the same VR settings for 2024 as you have for 2020 or not.
May I suggest backing your usercfg.opt and then setting everything in VR to low and seeing what you get. Then move up to medium and see how that compares.
The most obvious issue that I could potentially see is the 10GB VRAM for the 3080. 2024 uses more, I believe, and if you are having memory being swapped out then that could account for the sort of issues that you are having.
Welcome to the VR crashed my performance club, all you can do is lower your setting and run DLSS (if you can tolerate), I have a 9800x3d + 4090 and I got a big hit on performance also as other comment noted. If Asobo had been transparent instead of stating no performance impacts I’d have stayed away from 2024 until/ if it optimised
MSFS 2024 is demanding enough on older hardware but you have made it even more demanding by feeding it to one of the latest high resolution VR headsets out there.
If you want to see respectable performance at reasonable graphics settings and clarity in MSFS 2024 with that headset, you’re going to need an entire new PC running a latest gen CPU and 16GB+ GPU and fast RAM.
Interesting. I’m using the Crystal Light and have no issues and had a G2.. I did have issues (PC crashes and bad stutters) when I was running Steam VR for FS2024 and FS2020. I did come across Pimax XR Control Center per there support and it fixed the issues in 2024. For FS2020, I had to change anti-aliasing from TAA to Nvidia DLSS and, Full Screen. No issues. Graphics did look better with the Pimax OpenXR than it did with SteamVR.
If you are using the Pimax software double check to see if your room size got reset, everytime I start the sim it would reset my room size and if you are out of that ring (small room setting) you will get really bad FPS. If you move into the ring your FPS goes way up. I would guess it has something to do with the passthrough mode.
The problem is the memory of your and my GPU. The simulator already uses +12GB VRAM in the glasses in medium settings.If you set the terrain LOD to over 100 then it gets even more. In Ultra, the FS2024 already needs +14GB. A graphics card with 16GB VRAM would provide some relief. One with 24GB VRAM would be even better.The FS2020 uses max 9,7GB VRAM on ULTRA settings. If you fly in Ulra 4K or Glasses the Sim uses 36GB RAM and you need 48 or 64GB for best experience for the 2024.Sorry, but 10/12GB VRAM are not enough for VR.In the recommedet settings are not really true the craphic cards over 12GB needed.In future you need minimum 16GB VRAM.
It’s still a problem in 22/04/25. When I first installed FS2024 I did manage to use it OK in VR wirh a Quest 3 with no add ons, flyng the career path with RTX4090, Intel i9-13900K, 64Gb DDR4.. But as soon as you fly in more complicated environments with addons it gets too glitchy. Even witth DLSS, no idea why people complain about that, and medium to low graphic settings it’s still glitchy with a RTX5090. It’s rediculous. I just installed it again, the MSFS20204 marketplace store is still relatively poor with even updated 2024 aircraft not appearing. Stupidly I deleted my MSFS2020, I was a little unsure if that was interfering in someway but it looks like I’ll be going back to it. Anyone who enjoys playing on a flat screen with some sort of head tracking will be fine. By the way I used a Quest 3 with VirtualDesktop with VDXR runtine, and a Crystal Light with OpenXR.
On top of the poor performance, there is a eye rendering issue that gives me motion sickness instantly. Something is just “off” about VR in 2024. Some people are claiming great performance, it “feels” terrible on my system. FOV rendering looks like junk.
Im starting to wonder if Virtual Desktop useres are having better luck (Im on link cable).
2020 is playing better than ever…clear gauges, running AI ATC, simhaptics, and other extras. No FOV needed.
Beware of meta quest Meta Quest Link App Version 76.0.0.452.315 (76.0.0.452.315) Lots of folks including myself are having all kinds of issues with it. App taking forever to open, link will not connect, black screen when it does connect.
I gave up on the link cable. The official one doesn’t charge the headset while you are using it. I bought another cable that had a separate charging plug to it but the battery still went down. I got a very long cable that goes directly to a charger that, if I keep it plugged into the headset, keeps the headset charged but I lose the direct connect to the computer then. However, I found that using virtual desktop, my wifi gives me even better results than the direct link. Virtual desktop was a game changer to me.
