I have described each one of these VR streaming subprocesses, what they mean and what to do about them in my previous Virtual Desktop optimization article. Decode (blue) – the time it takes your Quest 2 to decode the compressed video again.Transfer (green) – Network latency (in case of wireless PC VR).Encode (red) – the time it takes the encoder (GPU) to receive the video frames and encode them.Here you should take note of the first graph (top left) and see which VR streaming process is taking up most of the time (and causing lagging): You will see something similar as in the picture below: In the bottom section, under “HUDs”, enable the Performance HUD in Oculus Link mode.Įnabling Oculus Link performance HUD (heads up display) will display a performance overlay when you are in VR. If you are an Oculus (Air) Link user, then go ahead and open Oculus Debug Tool (located at “C:\Program files\Oculus\Support\Oculus-diagnostics” by default). If after restarting your devices and resetting everything to default values, you are still experiencing lag with your SteamVR games, it is time to dive deeper into the potential root cause of the problem. Or you might also go with the route of uninstalling and then reinstalling the software. If you are unsure, then Google how to restore the default values. Oculus Software (Resolution, bitrate etc).Oculus Debug Tool (0-s are for default values).We want to start troubleshooting from a blank sheet and for this reason, it is a good idea to restore default values of: There are settings like that may work for one scenario, but not for others (or be outdated altogether). As it turned out, this was caused by previous optimizations done for Oculus Link (adjusting Encode Bitrate value in Oculus Debug Tools). There is a decent likelihood that your SteamVR performance issues are caused by misaligned and/or conflicting settings.įor example, there were thousands of people jumping in to test Oculus Air Link as it rolled out, only to be greeted by intolerable lagging for each and every game. If you have modified VR-related settings during your troubleshooting process or at some point earlier, go ahead and restore the default values. Sometimes routers just “get tired” after a while and need a small nudge, so make sure you try restarting. When it comes to wireless PC VR, I have also found that restarting the router is often an effective way of overcoming lagging and stuttering issues. This way you can be sure that all the changes have been applied and there are no other conflicting factors in play. Personally, I almost always restart my setup each time I try different fixes for either hardware or software-related issues on my PC. Starting from a “blank sheet” by restarting your PC and headset should be your default course of action each time you are facing unexpected performance issues. Based on this information you should get a pretty clear idea of whether your PC is the bottleneck or if there are potential steps you can take to solve your current problems. I have previously written an article listing the minimum and recommended specifications for VR gaming along with real-life user performance feedback for Half-Life: Alyx. Sure, sometimes lowering the graphics settings and tweaking configuration might get you a tolerable result with a low-end PC, but more times than not, you should be thinking about upgrading your hardware. I have seen so many people asking for help in forums / Reddit threads when in reality there is often not much they can do. And do keep in mind that minimum does not mean optimal. The first thing to consider when running into performance issues is whether your PC has good enough specifications for VR gaming. Without wanting to waste any more of your time, let’s get started! Make sure you stick around till the end of the article, where I share additional resources that could potentially help you solve your issues. To help you out of the ruts, I have compiled a list of steps you can take to hopefully solve your current lagging issues with SteamVR. Feeling frustrated and ready to pull your hair out because you simply can’t get your SteamVR games to perform properly? I know the feeling because I have been through this! (for Oculus Link as well as wireless PCVR).
