Lots of people are reporting this kind of poor performance in Alyx, whereas it played pretty smooth at launch. Something got screwed up either in a Steam update, SteamVR update, or Alyx update. The theory is that it is caused by the way, by default, the game attempts to scale fidelity dynamically depending on GPU load. Apparently when it adjusts fidelity it is causing loss of frames. The solution is to fix the fidelity level to a specific number at launch. So try this:Right click the game in your Steam library, then go to "properties" and "set launch options". Paste the following:If that fixes your problem then you can increase the fidelity level-novid -console -vconsole +vr_fidelity_level_auto 0 +vr_fidelity_level 3 +vr_render_scale 1.15
(fidelity_level 4, 5, etc... up to 😎 up until performance suffers.
