install vcredist x86 and x64 restart csgo &/or windows and come back if that didn't work ask staff or wait for a reply from them
Wow, that's really weird, generally I have almost no FPS difference between playing legit and playing with onetap injected.
Try is to improve FPS on csgo and trust me the image quality won’t be a big difference at all. Go to settings turn everything to low except the shader detail to high or very high. Try writing this in the console clforcepreload 1 can definitely improve fps. Also rdynamics 0 and r_drawtracers_firstperson 0 can give some extra fps. Don’t forget to save the cfg afterwards cause if you don’t when you relaunch csgo everything you typed in the console is for nothing.
