      Ever since the OpenGL version updated to 3.2, I have been getting a dramatical performance decrease on my machine. About 1/3rd of my previous FPS performance. I haven't set any hacky/weird settings through either my system, game or drivers that I can recall.

      I suspect this is an issue related to my graphics card (GTX 1070) or its driver, as the 21w10a screenshot shows OpenGL running version 3.2 rather than 4.6 as previous versions show. This does not seem to happen with anyone else I have seen online. I suspect my GPU is somehow forcing or emulating OpenGL 3.2 which might be why the game is performing worse.
