Starfield Performance Tweaks – 20 percent more FPS with the same quality
The first tweak is about the CPU Priority in windows. This works quite well most of the time, but can be potentially enhanced. For me it yielded about 1-4% more fps and also got rid of some annoying micro stutters.
The downloadable zip includes a file that changes the registry, so Starfield always runs on high priority. Its a very simple regedit with only two entries. If you want to remove the entry, I included an uninstall file as well.
The second tweak only works on Nvidia RTX 30- and 40-series. On my RTX 4070TI it improved the performance by a whopping 10-20%, depending on the scene.
It’s about a feature called resizable bar, that Nvidia introduced a while ago. You have to activate in on your system and then force Starfield to use it.
The zip includes a guide with screenshots and download links for the required tools.
