VR help please

[lahsoldier]

First of all thanks for reading this and any help would be appreciated. I have search on the forums and tried many things but still seem to come back to the same issues. Here is my problem...

 

I recently upgraded to a RTX 2070 and have an I7-2600 that at least in what I can monitor or tell can get up to 4.1-4.2 ghz. 16G or ram plus large page file on ssd (specs below). My problem I am having is during NON VR flights I have everything set on as the attached picture shows. I get pretty much a locked 60 fps dropping to 47 during hard turns, GPU load 32% , CPU total 55%, highest cores getting 81% briefly but normally averaging about 50-60 with other cores being lower. No issues with the flight at all. Works great other than I expected the GPU to be utilized more than that.

 

What I'm more concerned about is when I go to VR with EVERYTHING turned off, on lowest setting, if they cant be turned off, and all sliders to the left in settings except gamma, I get GPU usage of 35%, CPU of 60 (highest it goes), single core hits 45s at its highest, and get 30fps + or- depending on maneuvers.

 

Understand that this is all done with the Nvidia settings in its control panel being also either all off or on their lowest setting too. Why did I do that? Because even when the Nvidia settings were set to what is listed on these forums as optimal for VR it didn't make a difference in fps in VR. My pixel density in VR settings in DCS is at 1.0

 

Yes I have done the make sure its in full screen thing, the reload the graphics card drivers thing, check steam VR and set what I could in that though I really have no idea what those are. I'm at a loss. My expectations were I would have a CPU bottle neck due to having an older CPU and expected to have a usage close to 100% and low GPU usage. Unless I am not reading my results correctly I don't see that. Anyone who has any idea or suggestions please comment. I am running a Lenovo Explorer through steam VR and windows mixed reality set up. ALSO temps on everything are very normal (60s to low 70s on CPU max.)

 

 

Thank you in advance

My guess, it is your CPU, or possibly the lenovo. Ive got a way shittier gfx card system and can run a rift fine. But my cpu is a 4720.

High visible range, trees, grass combined with a high preload radius is flogging your RAM. Not sure what terrain texture does, I think it used to load up buildings for you, which doesn't help either. The terrain itself looks the same to me in VR. I *think* all that stuff is CPU and RAM but don't quote me on that. Dialing that back doesn't hurt VR much, I think a lot of that stuff is beyond VR resolution anyway, you might be rendering stuff you can't see anyway.

 

Far as the GPU is concerned, the most expensive stuff in VR is MSAA and shadows. You can get away with water texture and anisotropic filtering. And 1024 cockpit displays should be fine.

 

Suggest

1. Make sure you're only making one pass with supersampling. Note, PD is supersampling. So if you have a PD of 1.2 and you're supersampling in steam, you're flogging your card to death. Pick one.

2. Turn off all shadows and MSAA and see how high you can get PD.

3. If you can run it at like 1.8 or 2.0 without stuttering, you're golden. Me, I would back off on the PD to like 1.5 and see if I can add the MSAA back in. I get the feeling adding in a little MSAA can help cockpit readability. You can also work with the shadows. Not sure terrain object shadows do much but having at least some shadows is nice (wish I could do it but I can't)

4. But, if the most you can do with PD is like 1.4 or 1.5, I'd ditch MSAA and just do PD. Is what it is.

That doesn't sound right, I get up to ~28% CPU usage for DCS total up to ~34% CPU usage and GPU between 60 and 90% in NTTR and get 45 to 90 FPS mostly 90 away from Las Vegas with Rift.

 

My current settings here and PD 1.2.

 

Preload and clutter should use VRAM Shadows are a FPS killer but what is the lenovo res?

 

Be aware different maps and different aircraft will use more CPU/GPU usage especially FA-18 and PG map or Normandy map.

 

<edit>

I also turned off Rift processing and nvidia processing so it's all DCS controlled.

Did you go into steamVR settings, and lower the global application resolution slider to 100% in the video tab after checking "Manual override?" Do that first. Then tweak dcs settings. Also make sure you're not trying this in the mig-21. It's cockpit is causing me some fps loss. Make sure you're not on a mission with a bunch of static aircraft as well.. as one or more of them may have an issue causing an fps loss.. they may have fixed that much by now though I'm not sure.

Thanks everyone so far for your answers. Some of you mentioned turning down DCS settings. Maybe I wasn't too clear on how I did my experiment here. The settings I have on the picture is for NON VR playing of DCS with a track IR etc. I can get good normal frame rates with those setting with my current hardware. When I go to VR, is when I have taken ALL of the DCS settings and ALL of the NVIDIA settings to either off or to their lowest setting possible and is STILL get 30 fps and rarely peaks above 35. I can get those same frame rates with the settings in the picture but notice more pausing and other issues.

 

Headwarp… I didn't do that in Steam VR as I had no idea what that was but I have tried it since. At 100 I still get the same 30 fps and at any lower DCS looks like crap and unplayable. I have been doing all my testing on the A10 instant action mission easy (so Caucasus) Trying to keep the test bed the same for every test. Are there other settings in the steamVR that need tweaking? what about windows mixed reality settings?

 

 

Again thank for your help. This maybe as one of you mentioned, and I am basically coming to a conclusion that, its a CPU bottle neck, but the numbers just aren't showing me what I have read it should look like.

Bear in mind that you are pushing a lot of pixels with the Explorer . 60% more than you would in a Rift or Vive , for example . I have no WMR experience , but the pixel count was a very important consideration in my decision to get a Rift , bearing in mind that I am running a 1070 .
