SP or MP?

No. The memory bandwith on AMD cards is lower. The chose it, because it is cheaper and more power efficent. To overcome the small bandwith, they added the infinity cache 128MB direct on the gpu chip. The prediction for what to chache does not work as good as they thought. So in 4k where you need bandwith, the amds cant hold against the raw performance of the nvidia cards. The chose the just working method over new tech. Nvidia focus is on RT. But there is no card which can handle RT at 4k. DLSS is nice, but i think it should be 3.0 to get very good results.

You need very different settings for each different vr hmd. On your 32" it is also another story. SS is allways supirior to any AA. But more GPU heavy.

If something behaves weired, delete shader files from dcs. On reprojection with my pimax and pitool, i have allways half the native Hz of the HMD maximum!?

Dont forget to check MP, if you play that too.

@RedX Can you bench it with our bench setup from Maybe delete the shader files after swapping cards.

On our VR testing, the CPU utilisation was lower with amd 6000 cards. So there was more room for dcs.

Please never ever use any weird tools for driver cleanup. You can have both drivers in the system without any problem. If you want to deinstall any driver clean, boot in safe mode and do it there with standard windows tools. Windows knows best. It is not Win98 anymore.

I have also not the Steam version, but all the HMDs use SteamVR even for the non steam version. So you can start everything normal and just open fpsVR.

It is allways the SU-25. I think he choose it, because everyone can access it. With "a" you start the autopilot. After that you have to activate your fps counter tool of choice. We used fpsVR. There you first have to activate history in the settings. If they are on, you can open Settings->Basic. With the reset button you kinda start and stop. In your Windows document folder you can find the log files and the tool to view them.

You just have it on most HMDs. Best headset in cathegorie sweetspot was Pimax 5k+ so far. There they build 5 or 6 interations of lenses. Each tooling for a new lens cost 150k$. So it is easy to safe a lot of money there. As i know from my camera change from 6MP with good lenses and perfectly crisp sharp pictures, it was a total mess when switching to 16MP. It is a lot harder to build good lenses for 8kx/G2 than for any other HMD.

8kx DCS VR standard settings SP The 3080 with FVR had 5 FPS more than 6800xt. Look at our big benchmark thread here. If FVR is not fixed, it will add another layer of delay to it. Non fixed vs. fixed will not improve your FPS. It totally makes sense to use fixed FVR on headsets like pimax 8kx and G2, because the edges are blurry anyways. So why render that blur stuff in full quality? Edit: Had a look at it in MP. There it looks different. Fixed FVR adds additional stress to the CPU (5900x) so ends in worse Framerates because the CPU cant deliver it. So fixed FVR with Pimax doesnt help in MP.

The benchmarks were tested in SP. Both cards only filled around 7GB of its vram. So that is no issue in this benchmarks.

He mentioned it himself.. The pictures are from different benchmark runs. The 6800xt is under all circumstances supirior to the 3080 in DCS at the moment, frametimewise.

@K1nsal We will bench the G2 on the other systems aswell. So if there is any unknown problem, we will see it.

Good that you buy what makes sense for you and not only what you think is best. I am happy to be back on full AMD. The stock 6800xt is a really good card, performance and noise wise. I would buy any 6800xt if you can get them for a decent price.

You will get a lot more for your money with 5600x instead of 5900x especially in SP. The 3800x is somewhat bad, because of the 105W TDP (3700x has 65W) it is a hot CPU which needs a very good cooler and is not really faster than the 3700x. I think with 3800xt it will be the same problem. You should check that. So i would go 3600x, 3600xt, 3700x, 5600x. 5900x is only worth it, when you dont care about the price. Maybe 5900x is helpfull in MP. I think we will do a short comparission. But first we have to fly a little bit

Placeholder Frametimes

We will test my old System with Ryzen 7 2700 and GTX1080ti.

The Timings of that Ram are: CAS Latency CL 19 (entspricht ~10.56ns) Row-to-Column Delay tRCD 20 (entspricht ~11.11ns) Row Precharge Time tRP 20 (entspricht ~11.11ns) Active-to-Precharge Time tRAS 40 (entspricht ~22.22ns)

It is from my old system. They where pretty decent then and offered great speed for 180€. With 4 off them, i have the same FPS like the test with 3200MHz fast CL kit. But we will bench that also with the other systems.
