Caution
- We've been informed about some FAKE websites presenting themselves as OptiScaler team, so we would like to strongly highlight that we DO NOT HAVE an official website!
- We DON'T have an official manager app, so please be careful when downloading or using them! And please don't bother us to provide support for something which isn't even ours!
- Only LEGIT places are this Github, our Discord server and Nitec's NexusMods page.
- OptiScaler is FREE, any kind of monetary requirements are scams!
Warning
VERY IMPORTANT!
- The new BAT should automatically display a warning if you're updating from an existing Opti 0.7.9 install, deleting the old files is required due to file changes with bundling.
- Linux users will need to manually remove
nvapi64.dll(and probably nvngx.dll if present) along with any old Opti version! - Necessary step to ensure everything works properly since OptiScaler now comes bundled with Fakenvapi (renamed to fakenvapi.dll)
What comes bundled:
- OptiScaler 0.9.1-final - Signed build
- Fakenvapi 1.4.1
- Nukems dlssg_to_fsr3 0.130
- FFX 2.2 SDK - FSR 4.1, FSR-FG 4.0.0
- XeSS 3.0.1 SDK (upscaler still reads 2.0.2, MFG is still Arc only❗)
What doesn't come bundled:
- FSR4 INT8
- which is required for any other non-RDNA4 card!

- Fixed the Vsync freeze/crash with XeFG (thanks to @FakeMichau)
