Part 7: Final Thoughts – The Definitive Way to Play

Frequently Asked Questions (FAQ)

Q: Does GTA IV Pro Fixer work with the Steam Deck? A: Yes, but you must install it via Proton Experimental. Set DXVK = false in the .ini (since Linux prefers Vulkan) and let the mod run in DX11 mode.

Q: Will this fix the "RMN40" (Windows Live) error? A: Yes. The Pro Fixer includes a full GFWL xlive.dll emulator. You will never see the Microsoft login screen again.

Q: My FPS is still dropping in Times Square (Star Junction). A: That is a CPU draw-call limit of the original engine. No mod can make Times Square run at 200 FPS. The Pro Fixer raises the floor from 25 FPS to ~55 FPS in that area, which is the maximum physically possible.

Q: Can I still get Steam achievements? A: No. Because the fixer disables GFWL, achievements are offline only. If you want achievements, you must play the broken vanilla version.
