optimizing GPU and CPU for Assetto Corsa

I'm trying to find out if my GPU, CPU or RAM is the bottleneck in increasing AC graphic performance, any one have tips?

I remember there was a video or post from Kunos regarding looking at some in game app info and that tells you whether the GPU is at full capacity or not, but can't seem to find it.
Anyone have that info?

 

First things first.

What CPU, GPU, Memory do you have?

There are many variables in order to find out what would be your system bottleneck.

I used MSI Afterburner combined with RivaTunner statistics server to check GPU, CPU usage. I used a replay I have where I saw low GPU and CPU usage, signal of memory being my bottleneck. Run the AC benchmark and share your score.

If you have 8Gb of RAM you should be fine, I have 8Gb and can do 50+ cars without RAM being a problem.
Just open the app that has an "FPS" on the icon, if the "PHY" value is over 100%, your CPU is the bottleneck (Although you'd get the warning on screen if that happens, so you don't even need the app for that).
If the FPS is below 60, and you're noticing low framerates without getting the CPU warning, then the GPU is the bottleneck.

Edit: It also depends on what you're missing. If you wanna be able to race against more AI opponents, upgrade the CPU (it will have an impact on GPU as well, but not as significant). If you want to have more video quality, then upgrade your GPU.

But if you're planning on buying ACC, I'd definitely wait until it's released before upgrading.

 

+1 on the MSI afterburner comment. It's a very straightforward tool showing you everything you need to know on CPU usage, GPU usage, temps, clocks etc.

Don't forget to do your basic homework before getting too complex: deactivate Windows' fancy graphics options (window transparency, desktop graphic effects), deactivate any unnecessary background services via msconfig, have all your drivers up to date etc.
