only discovered Reshade and it's wonderful, thanks!
i'm having troubles with on/off toggle in STALKER games. somehow it mysteriously worked 3-4 times (start the game - perfect toggle throughout), but 90% times it didn't work (start the game - no toggle at all throughout). tried with 2.0 and latest previous version. please help!
figured it out - you need to switch to desktop during the game (alt+tab), then back to game and toggle is fine
