Here are the key things you will need to do to make FO3 run smoothly:ġ) Disable Vsync in your.

I’m also not going to cover what FOV settings to use etc., because those are all going to depend on your HMD and personal preferences anyway. I’m not going to give step-by-step instructions here, because if you need a true step-by-step for any portion you can easily find it already written-up online many times over. So everything here will probably apply to you but you’ll likely need to to use one of the various fake-frame methods (brainwarp, async, fluid sync etc.) If you want to achieve true 90fps you might have problems anyway, as the FO3 engine will experience significant issues when pushed above 60fps. I’m only shooting for acceptable lounge-mode performance here with – not full VR. This is running a Pimax 5K+ HMD, so I have to run relatively high resolutions to really make use of the Pimax. So pretty capable, but definitely not top-end by VR standards. So I thought I would put my finding here in case other vorpX users want to get it running well.įor reference, my rig is a Quad-core i7 overclocked (and liquid cooled) to 4.4 ghz, 16GB ram, all SSD storage, and an RTX 2080 Super card. For those who don’t know, titles based on that engine (so at least FNV and Skyrim, plus probably others I don’t know about) had all kinds of fundamental game-engine-based frame-rate and stuttering issues, even on vastly overpowered rigs. I finally had time to sit down and really tackle getting Fallout 3 to work properly with vorpX.
