It’s not advisable to put the link cable display cable on usb, it works best on the display ports of the graphics card.
also FPS issue may be caused by legacy 32 bit WMR,
This is from a redit post.
All graphics problems FIXED! HP REVERB G2! No more stuttering!
I can't explain to you all how much I despised windows before this, but now? INFINITELY MORE.
I stream, and using a program called OVR toolkit to see my chat, and it was TANKING my fps just looking at it.
My gaming rig is a i9-9900k 3.6Ghz, EVGA 3080 FTW3 Ultra, 64 gb of ram, ASUS ROG Maximus XI Extreme Z390 motherboard - I couldn't get rid of stuttering in games, with ovr, without ovr, it was driving me mad.
I contacted the developer of ovr, his name is Curtis, unbelievable guy, replies straight to you on their discord, and rolls out changes so fast it is something to behold. He told me to run half life alyx, ovr, and report back on how much gpu ovr was using. Well I did it, opened task manager, and ovr was only using 6%, Alyx obviously more, BUT WINDOWS DESKTOP MANAGER WAS USING 30% TO 40%
I Googled it and found someone saying checkout scaling options in display setting, I went in there and I have THREE NEW DISPLAYS besides my TV. I told Curtis and he was like holy shit, you're in WMR? And I said yes, and he linked me this:
He told me this:
Those additional desktops are 'virtual' desktops.
WMR creates them for use with it's own desktop viewer.
Per the above link, you can disable them with a registry entry. It's possible it's adding to the issue.
As you're rendering even more displays.
So I did it, searched the article for disable it popped up followed the steps in the registry, restarted the PC and BOOM! It works!
For windows desktop manager to be using 40% of my beast of a GPU is absolute INSANITY. I stream from a second computer, an iMac to avoid the madness that is windows, this is unreal to me that it's even a feature Jesus Christ.
TLDR Windows is the bane of our existence. WMR is rendering 3 additional screens at all times and eating up all your GPU, Curtis of OVR Toolkit helped me fix it all credit goes to him. Go to this link: https://docs.microsoft.com/en-us/windows/mixed-reality/enthusiast-guide/using-microsoft-edge#monitor-and-input-handling-issues and search the word disable to disable virtual monitor pre-allocation.
And support OVR Toolkit here! I am not affiliated with them in any way whatsoever, I'm a stand up comedian who also streams on Twitch haha https://store.steampowered.com/app/1068820/OVR_Toolkit/
Happy gaming everyone! The headset is a wonder! The controllers are an abysmal failure though (tracking), I hope they fix that.
