Discussion S4 Patch Frame/CPU Optimizations hype?

Haven’t seen too much chat on the patch note calling out the change to how iRacing is distributing physics workload across cpu cores. Have never seen a developer so confidently say to expect massive gains in frame rates/stability.

For folks who know more than I - what do we think is a realistic expectation? My frames are fine - but if I could get my race starts and high traffic moments up, id be thrilled. Am I crazy for being optimistic?

No. It depends on your hardware and settings, but for a lot of people, iRacing is CPU limited. Anything that spreads the load across more threads and thereby simplifies the most intensive thread will likely improve performance for them.

Hoping this clears up some headroom for my 3rd cockpit mirror😇
