From what I recall, AC is unfortunately not optimized for multi-core CPUs like yours. Everything runs on only one core, so single-core performance is king. The Zen 2 processors like the 3700 you have are notoriously weak single-core CPUs - fantastic for multitasking and for (rare) multi-core optimized video games - not so good for the much more common single-thread reliant applications like AC.Hi I would like to let you know about a problem I am having with Assetto.
I have a rather efficient PC but I cannot exceed 60 fps in races with 30 AI. I realized that my CPU and GPU are only running at 30%.
Do you know if an adjustment is restricting the machine ?
My config is as follows:
AMD Ryzen 7 3700
Nvidia GTX 3070 TI
32 GB of RAM
Thank you for your comeback
Open up Afterburner and take a look at the readout - make sure to enable each CPU core in the overlay, and CPU0 in this case is the one to watch. Keep in mind that the "Overall" CPU usage isn't helpful in this case - the rest of your cores could lay dormant, while CPU0 is overloaded - and it would still show as something like 30%.
If the slowdowns are happening because your CPU0 is overloaded (99%), that means that you'll likely have to lower the AI count. I can get slowdowns in a field of 24 if AI get into a huge accident on my 9900K 5 GHz, which is a significantly stronger single-core performer.
