Weird stutters in DirectVR Mode

[stas336]

Recently i bought vorpx license and tried to play in HL2 and Mirrors Edge on my DK2 in DirectVR Mode. After some seconds textures start to jump even if you standing. I dont know how to fix this issue. My ingame fps is constantly around 74-75. Also without enabling DirectVR mode everything runs fine.
My Hardware:
OS : Windows 10 Pro Build 15063 x64
Processor : Intel Core i5-3470 3.2 Ghz
Videocard : Nvidia GeForce GTX 1070
RAM : 8GB DDR3 1600 Mhz

did you go in bioshock ini file to change the resolution to be in what is recommended for vorpx.. that helped the stuttering on my computer a lot.

C:\Users\yourusername\Documents\My Games\BioShock Infinite\XGame\Config
XUserOptions file scroll down
this is minimum requirement for vorpx for 8:9 ratio

ResolutionX=960
ResolutionY=1080

I hope it works and it should.. but 8gb ram for vr is only the minimum requirement for a lot of vr apps so haven’t tried it

I thought that 1280×1024 is the best resolution for DK2 kit, not 1080×960, so i applied it in HL2 and Mirrors Edge. 8GB is optimal choice, because only 5GB used in VR gaming. Do you have DK2 or CV1?

[bob24]

make sure your resolution is inversed in the file I showed you it should play better.
I use a cv 1 r9 fury and 16gb ddr4 and a 6700k
ResolutionX=960
ResolutionY=1080
or
ResolutionX=1024
ResolutionY=1280

Why it should be inverted? Vorpx showing me that optimal resolution is 1280×1024, not 1024×1280.

I set my resolution and other parameters ingame menu (HL2 and Mirrors Edge) and it works fine, except stutters.

until you actually do it you wont see a difference with your system.
if you really want to know why after you can read this it is too technical for me to explain even why but it works.

Performance/Quality Tweaking with Custom Resolutions

I tried this method in HL2 and Mirror’s Edge, but seems that they don’t support 8:9 aspect ratio. So stutters are here with me again.
