I am playing on a intel core i5, 8gb ram, with a AMD Radeon R7 200 series GPU. I used to play this game with no lag problems, i decided to download it back because i saw someone on yt play it and wanted to start it over and play it again. i downloaded the neurolink test version and picked "i have a weak pc" and turned off motion blur. the lag was terrible. idk if my pc is just that bad but when i used to play it was silky smooth. after that i thought the neurolink version was just too strong for my pc. so i booted up the original. the lag was still horrible despite me picking the i have a weak pc setting. and it didn't make much of a difference.
