Hello Obi team,
We are experiencing an issue where the same Unity scene runs at a low FPS only on a specific machine, while we believe it shouldn’t according to the specs.
Running on Windows 10 pro, unity version 2021.3.8f.
On one machine we have
AMD Ryzen 5900X processor (12 cores, 24 threads - overclocked to 4.8Ghz)
Nvidia RTX 3080
32GB RAM
With this machine our scene runs at 60-70FPS. Disabling the Job Debugger and safety checks doesn’t seem to make any difference.
On a new machine we have
Intel i9-10980XE Extreme (18 cores, 36 threads - 3.0GHz, no overclocking)
Nvidia RTX 3090 Ti
128GB RAM
With this machine the FPS of the scene goes down to about 15-20FPS.
We tried benchmarking the new machine with 3D Mark and it seems to work as expected.
Is the difference between the two CPUs so vast to justify such a drop in FPS? Or is there another reason such as the increased number of threads?
Or can you think of anything else?
Many thanks
