I'm reporting an issue I'm experiencing with this new update.
Good to see so many fixes on this update list though.
But since I installed this update yesterday, all of my games performance all of sudden becoming very bad, or straight unplayable.
In HL Alyx, even moving in small corridors will cause very bad lag and stuttering, this also happened in Skyrim VR and Boneworks (so far I've been testing) - as well as playing any game in Virtual Desktop.
I reverse my system back to a point just before I update to 1.0.12.4a, and everything is back to normal. So I'm sure it's somewhat related to this update.
Maybe there's something still need to be fixed regarding the update.
