Someone explain to me like I’m 5. Have Rebirth on PC and can’t figure out for the life of me why the frametime graph looks like this.
Some context:
CPU: R5 5500
GPU: 9060XT
16GB RAM
Installed on SSD
OS: Bazzite
FPS locked to 60 to help the game “feel smooth”
All settings at max (1080p) at 100% min/max resolution scale
Also using optiscaler to inject FSR4 over DLSS
I also am running a 1080p FreeSync monitor 180Hz but like I said I locked it to 60.
When I’m stationary the frametime graph is flat but when I spin around it goes crazy. I have the engine.ini mods installed as well but it doesn’t seem to fix anything. When watching benchmarking videos, other peoples graphs look stable including on similar hardware. Is it really down to it just being an unoptimized game or is there more to it?
Thanks in advance.
