Easy performance boost and fix for most problems (works on all three definitive edition titles).
Start Options
- Open your Steam Library
- Right click the game’s title and select Properties
- On the General tab you’ll find Launch Options section.
- Enter the launch options you wish to apply and just add “-dx12″ (without ” “).
- Close the game’s Properties window and launch the game.
Note: Your GPU needs to support dx12 (almost every gpu does support it).
Little Graphic Setting Tweak
Biggest impact on performance:
- Car reflections: set to “screen”
This almost doubled my FPS.
Some smaller impacts:
- Visual effects: set from “Ultra” to “High” (almost no visual difference)
- Cloud quality: set to “Volumetric” (almost no visual difference)
- World shadow quality: set to “medium” (has a visual impact)
- Streetlight quality: set to “medium” (has a visual impact)
- Vehicle light quality : set to “medium” or “low” (has a visual impact)
You can also set all settings from “Ultra” to “High”. This will have little to no impact on visual appearance but it will give you a more consistent framerate.
Now I can actually get +60FPS while driving in the city, THANK YOU.
Just changing car reflections to screen helped! Thanks man.
DX12 actually a good idea
I’ve set everything on high though.
On Ultra its freezes like hell but on high – working like a charm
Frames were dropping like mad on GTA 3. Setting Car Reflections to Screen, worked and game is playable. Thanks
