what ive tried:
reboot computer
yell at discord's horrible video capture that tends to cause microstutters (it actually wasnt its fault this time
switch from opengl to vulkan
turn on hybrid ubershaders (that just destroyed my framerate in a normal way)
demand all shaders be compiled before loading the game (both in conjunction with hybrid and not in conjunction with hybrid)
pcsx2 did do this for a bit but it mustve been shader stuff cause it stopped after a while of playing (spyhunter 2)
might have to jump over to the ps2 version of Spyhunter
