VIVE Framerates

[zafgev]

Can anyone please confirm the following for me. When using Vive VR and you have the DCS framerate counter going - what framerates to you actually see going? Some mention 45 locked and also 90. However I get between 30 and 40. Never have I seen more. Last night I set settings to Low then everything turned on - High - and the framerates stay about the same. The flying experience is smooth however - not choppy - so I'm guessing its pumping out frames ok but the counter seems low compared to what others are saying.

My rig is running a i7-4770K, SSD's and GTX1080 and my in VR I run at 1.7 sampling rate. I'll be updating the video card drivers tonight but not holding my breath. I'm still keen to understand what others are seeing as far as FPS counter is concerned and if changing display settings makes any difference to frame rates for you. Thanks guys. Always fun flying with you.

1.7 might be a bit high. I have GTX 980Ti (same CPU as yourself) and bring SS down to 1 with MSSA on 4X textures on medium and terrain on high with pretty much everything else off. This seems to work best for me. But also defo delete and update old nvidia graphics drivers I was (use display driver uninstaller) having all kinds of problems until I did that.

I get 45 on DCS 2 and pixel density 1.4. This can drop up to ten fps with an AC like the Mig21.

Wait... Does the pixel density slider in the options work for Vive now? Or are you running forced pixel density through the config file edit?

The slider works since 1.5.5. As well as VR Zoom on the Vive.

Here are my settings, and I run also run pixel density at 2.0. Framerates stay consistantly around 45-60fps, but of course do dip down into 30fps on occasion depending on how intense the server is at that moment (I only really play multiplayer). This makes things in the cockpit super clear for you, and frankly anything outside of the cockpit will never look super sharp due to the screens/lenses in current VR anyways so you don't miss out having everything set low there. The one downside is no shadows I guess, but those things are unnecessarily demanding on the hardware so I've gotten used to not having them (it's really not that noticeable).

 

One big change I did though was opt into the steamVR beta, and I highly recommend you do that, it gives access to Asynchronous Reprojection (basically ATW for the Vive). It makes the game way smoother when you turn your head, just not when you lean your body. It's a big change and allows the game to run just a touch higher than 45fps for the most part, instead of cutting you down to 45fps as soon as it can't hit 90, which DCS can never hit.

Thanks - yes I'm running SteamVR Beta and yes the "Asynchronous Reprojection" setting makes a huge difference. I've noticed you do tune down a lot of settings - some of which I have at higher settings. I'll try some of yours. Also I'm keen to know if setting the Resolution makes a difference. I've noticed you are running at a very high resolution even though you have a 1080 monitor. I've always wondered if mirroring the VR displays on the monitor creates overhead as technically I think they (VR and monitor) would be running at different resolutions so the graphics card is rendering for both?? I'm not certain - does anyone know? Is there a way of turning off the monitor mirror of what you see in VR?

Oh, I actually need to update that, I have a 4k monitor now hence the high resolution.

 

The game gets rendered based on the HMD's resolution and super sampling value then that just gets mirrored on the monitor, the monitor doesn't get rendered separately, it just get the image that's rendered for your left eye (or maybe right eye, idk).

980ti here.

How is that possible? I have a 4k monitor and get much better performance than that on a single 980ti. Shouldn't a 4k monitor be more demanding due to the higher resolution?
