On Roman Design’s thread it seems that in VR with the G2, depending on CPU, we will finally be able to rock at 100%OXR and TAA100% with Motion Reprojection set at 45fps. This with a mix of high and ultra settings. Can’t wait to get my Asus Tuf OC 4090 delivered so I can confirm.
As I have an AMD x570 motherboard and the 5800X3d CPU, I’ve had to buy a version 2 cable, as I was still using my version 1, using the USB C connector on my Radeon 6800XT. The AMD x570 USB bug meant that every other USB port on my rig would not power up the G2 headset with the version 1 cable and none of the newer gen cards will have a USB C connector on them. The version 2 cable seems to fix that.
may i ask, how many extra fps are you getting with the 4090 compared to your previous gpu (3090?)?
my 4090 arrives today, i will post my fps difference.
People with Varjo Aero and 4090 report severe ghosting/tearing/stutters even with VR desktop applications, the issue is currently being investigated. Do you see such effects with your HMDs?
@agro1986,
1) What tools are you using to gather frametimes and then plot them. I was using CapFrameX but I want to compare with your results (I have a 9700K@4.8Ghz+3080ti+Quest2)
2) The spikes every few seconds cause us some visual pauses/stutters - are you running Win 11 22H2 - or are the stutters from MSFS? I have run a freeware app called TimerBench and it shows the same kind of high frametime stutters. Your 4090 seems like it has less spikes.
Thanks so much for the wonderful information! This can help all of us think about our VR performance carefully (which is quite hard to do). Correct me if I’m not reading the plots correctly but it seems that the 4090 provides about 4 milliseconds of improvement.
@SearBreak225638 The tool the plots are from is Nvidia’s FCAT VR. It’s pretty much the gold standard tool for VR benchmarks. We just don’t get them very often…
Some notes: When running the installer it will print some error message but it works fine. Also to get the viewer running you must install python and some libraries which is described in the guide, but if you encounter any problems you can ask me since we need more data-based benchmarking (many people said that DLSS has no performance effect, but clearly in my case the DLSS options all affect performance, with reducing quality all improving frame times).
You are correct to conclude that 4090 provides 4 ms of improvement (vs 3090) in the tests that I ran.
Regarding frame stutters sometimes it’s really random, if I restart MSFS/PC sometimes I get stutter free experience, but on another restart I get mostly the same frametime but with random stutters now and then on the exact same scenario. I’m running latest Windows 10 so perhaps the difference is stutter profile (compared to yours) is because of that.
No ghosting/tearing with quest 2 and vive pro 2. I sometimes get stutters every few seconds, but when I restart MSFS/my PC sometimes I get stutter-free experience.
I have a 4090 with G2 and FS2020 is unplayable because of tearing when I move my head. Actually the tearing is there in both WMR portal and steamvr portal … I’m kind of baffled. So many moving parts in VR.
I feel you. Many brittle moving parts and 1 bad link can ruin the whole experience.
Made a gameplay video with Vive Pro 2 using 3532x3532 resolution per eye (basically 200% of Vive Pro 2’s panel resolution, or 267% of G2’s resolution) with a mix of ultra/high settings. Mostly 45 fps with some hiccups.
For the best testing scenario, make sure to actually reboot your PC, start MSFS first , start a test flight, and test with nonVR that moving side-to-side inside the cockpit with the mouse(right-button) is smooth, and then start VR. That sequence (especially the reboot) seems to be required to get best and most consistent results.
installed my 4090, i’m experiencing atleast a 50% increase in fps over my 3080TI. at 125% TAA I am cpu limited, i’ve upped it to 175% (resolution is now really high, i’m using a 4k per eye 8KX) and i’m gpu limited. just as i thought. even with an old i7 7700K i am gpu limited at very high resolutions. if i play my games at high res i don’t really need a cpu upgrade, not just yet
Are you experiencing any of the tearing/stutters/ghosting that Varjo Aero users are reporting, including one who also saw this with his 8kx at large FOV setting?
Just as an aside, why are you pairing a 4090 with an old 7700K? I upgraded my 7700K a while back and it made the world of difference for my 3080 at 4K. A CPU upgrade for you would be a better investment than a GPU upgrade, particularly for VR.
Yeah that terrain sideways motion at low altitude is the true test of smoothness! For me everything g is pretty ■■■■ smooth except that ■■■■ stuttery terrain
