Choppy framerates with release 0.8.0

[Gagert]

Previously I used build 4200cfa (which I compiled from the source code) on Windows 11, and the framerates was decent using that build on Windows 11. With release 0.8.0 however, in both the windows-x64 & windows-x86 releases, the framerate is very choppy; it's like running the game in Dosbox.

The framerate seems to be choppy once you turn your car either left- or right. When driving straight forward or standing still, there does not seem to be any "choppyness" at all to the framerate.

My system specs are quite decent (not to brag), i7-12700KF, GTX 1080 Ti, only SSDs, 64gb DDR4 RAM. Can this have anything to do with the changes from June 2024 in the Changelog?

--i don't experience this with far older specs, so its likely something specific to mixed capability cpu's such as the 12-14th gen parts.--

Correction, i do. It seems like theres jitter in the viewport that needs interpolating

Hi, most likely the tear you see is due to the fact that physics frame-rate is different than rendering frame-rate. The physics frame-rate is also responsible for all the viewport transformations so you see it choppy.

Try to use this command-line arg:
--physics-step-time=10

It sets the physics engine to work at 100 frames per second. The default value is 40 which gives 25 frames per second.

--physics-step-time=20 seems more true to the feeling of carma95

The --physics-step-time=10 line inserted into to dethrace.bat file I made seems to do the trick. Maybe this could be the default setting going forward in newer commits of dethrace?

I could close this issue now, but would it for the community be more beneficial if I left this bug-report open, at least until this eventually becomes the default settings of dethrace?
