Playing PC 2D games smoothly at playable frame rates?

[theSelf]

Hi

Just got Virtual Desktop.. Wanted to see what playing some of my PC games like Battlefield V or anything for that matter plays on a virtual massive screen using my HTC Vive but on starting eg. Battlefield V the frame rates drop drastically.. Maybe only 1 fps.. what are suggestions for optimizing for playing games at playable frame rates? I have a super wide 32:9 5120x1440 monitor.. Can you get games just to play on the virtual screen in Virtual Desktop only and not play on the monitor as surely in general if my system is playing on both the monitor and my VR hmd it becomes too much for my system to run at playable frame rates or is the only way to drop the graphics settings and resolution when playing in Virtual Desktop and or drop the resolution on the monitor..?

Also wondered about how and if you can play 2d games that support stereoscopic 3D (like Nvidia 3d vision supported games) in stereoscopic 3D how you set that up to work in virtual desktop too?

Thanks for any feedback or links to resources as currently if I can't use it to play even 2d games at playable frame rates whilst still being sharp enough to see clearly I need to refund this before my two weeks are up..

Thanks!

You need to use Windows 10 to play regular games. You might need to lower the resolution a bit (it won’t make much difference visually to run at more than 1080P in VR). Also to reduce the GPU usage of Virtual Desktop, lower the supersampling to 1.4 and disable MSAA and environment mip mapping.

To play 3D SBS games, I recommend ReShade or TriDef 3D. Simply press F7 once the game is running to toggle SBS mode

Thanks..I am running Windows 10 (home 64bit).. So I do need to lower the graphical settings..hmm.. my second monitor is a 16:9 4k monitor.. Maybe I should run them at 1080p in that more normal aspect ratio but really was hoping not to have to mess with the graphical settings every time I play in VD and then changing back to the normal settings when running them normally on the monitor in non vr.. was really hoping there was a way to not display on my monitor at all in VD and only see the virtual screen in VR only without displaying to my actual real monitor.. This isn't possible? So there is not a sbs stereo 3d mode at all in virtual desktop as I was under the impression there was or is that only for 3d movies only and not games?

Just confirming.. So there
definitely isn't a way to stop my PC 2d games running in normal full resolution on my monitor simultaneously so all the GPU rendering mostly goes into rendering it within virtual desktop only and none to the real life monitor? If the option to turn off real monitor game rendering isn't yet available are there plans to add this feature in future if it will radically reduce the demands on the GPU? (I'm not sure I want to keep VD if I have to keep changing the graphical settings every time I change between playing 2d PC games in VD and then back to my real life monitor and have 3 days left to get a refund.. That said if I refund it I may get the Oculus quest version instead for my newly acquired Quest as that version of VD may potentially be more useful to me for playing steam vr and Oculus rift games wirelessly to the Quest so long again doing so doesn't require a radical reduction in graphics quality inn order to do that.. Hope you can reply asap.. Thank you

You need to render to the monitor otherwise there’s nothing for VD to capture. Capturing the monitor is essentially free (the game isn’t being rendered twice). What’s expensive playing a game in VR is doing the distortion, rendering the environment, etc. If you streamed a 2D game to the Quest, that part would be done by the Quest itself so you’d save a bit of horsepower but you’ll get very similar performance as playing with a PC VR headset. Hope this makes sense.

May I ask a question regard VD's super-sampling?

If VD captures what shows/renders on my monitor,how VD’s super-sampling works?
Does it GPU taxing?

For example

If VD's super-sampling set to "off", a full screen 1080P non-VR game rendered on monitor will be captured at 1080P and be sended to VR set for up/down scales.

If VD's super-samplingset to "2", does a full screen 1080P non-VR game will be captured at 2K and be sended to VR set?

I mean unlike OculusTrayTool which would change the render resolution of VR games, it seem that VD doesn't change the render resolution of non-VR games directly.

It is curious to me that how VD’s super-sampling works and does it GPU taxing.

Really appreciate.

With Oculus headsets, the supersampling setting in Virtual Desktop or in Oculus Tray Tool has no effect whatsoever on the desktop image quality; it only affects the environments. This is because the desktop image is rendered with separate timewarp layers which are at the highest quality already

I got a game working- it goes into its own mode for playing games (different mode to working on my computer's desktop) but it seems you can only get so close to the virtual screen in games by looking at the bottom left to change screen size- the last size being cropped in, which isn't good as I can't see info/details outside the crop ..(unlike when browsing the desktop which seems you can get really close distance wise- is there a way to get really close to the screen when playing 2d PC games to minimize the screen door effect as the screen door effect is off putting and makes me not want to use VD to play games but if the screen can be closer and the SDE reduced it will be more appealing.. thanks again

I tried the game settings option to try and add a couple of game .exe files but a few of them like 'Squad' and other similar multiplayer titles don't run as they come up with an anti cheat message as I think the software thinks VD as a 'foreign' software may be a way to cheat in games - is theer away to avoid that?

I realize the time I played the game in VR but couldn't get close enough I launched the game in steam vr theater mode and had nothing to do with VD- so I'm most interested in how to launch games within VD via the 'games' tab section and not get errors trying to launch.. thanks

This is described in the FAQ: disable Desktop Game Theater mode by going in Steam to Settings, In-game and uncheck the "Use Desktop Game theater..." option. You need to be using Windows 10 to play games

Thank you- just figured that out
