Optiscaler OptiScaler.dll (named as dxgi.dll) breaks RedScript Mods

[patricklupo]

*** Thanks for creating this Excellent util as it's Very Well made and far better than RenoDx + Reshade method ***

Issue experienced:

• Latest Reshade 6.8 no longer supports Cyberpunk Redscript mods but,
• Reshade 6.6.2 does support Redscript mods so is recommended by the Cyberpunk community
• https://www.reddit.com/r/cyberpunkgame/comments/1qshnj9/when_i_install_reshade_redscript_fails_to_compile/
• Redscript mods continue to work fine if Reshade 6.6.2 dxgi.dll is renamed to d3d12.dll
• But Redscript mods break as soon as Optiscaler.dll is installed as dxgi.dll
• It's unclear whether Optiscaler is incompatible with Redscript or incompatible with Reshade 6.6.2
• Screenshot of error: https://ibb.co/zWTmp0ks <- note that this error does not occur unless Optiscaler is installed

Cyberpunk install is using the latest Redscript, ArchiveXL, Virtual Car Dealer, TweakXL and Codeware
The majority of Cyberpunk's (currently 3100) mods depend on Redscript, which has not changed since last year (Sept 2025)
Please let me know if there's any additional details or fixes to try?

I'm pretty sure it's redscript because I'm not using any reshades and I'm struggling with the same issues atm

Agree. I tried again w/o Reshade; Optiscaler + Redscript are all that needed to produce mod compile error occurs.

• Redscript works fine with Cyberpunk's over 3000 mods alongside every other script engine (ArchiveXL, Cyber Engine Tweaks, Codeware, Cybercmd, TweakXL)
• Optiscaler works with Cyperpunk but without the majority of mods

• Also migrated everything to Nexus' Vortex with zero conflicts and same error

Update: While Redscript displays the compile error dialog during Cyberpunk startup, I found that those scripts (the one's I've tested so far) still work in-game. So this issue isn't a showstopper but more of a nice to have. OK to close IMO. Thanks again for the great DLSS5 mod!

Final Update: I zipped and uploaded a crash report to Grok and it successfully identified the following mods as the cause...

• cybercmd
• Vehicle Explosion Crash fix
  Removing these mods completely fixed this issue as well as made the game much more stable.
