precisely, but if youre on Linux, the kernel needs to be recompiled at ~1000HZ
I just tested this by disabling mmtimer in addons\metamod\plugins.ini while leaving sys_ticrate 10000 and the FPS sits at 500fps, so I guess you're wrong, still requires a booster to achieve 1000FPS (sys_ticrate 10,000)
*Tested on Windows 10 Pro Version 1909 OS Build 18363.1379 with latest ReHLDS and ReGameDll
