Surprised by Python apps

After switching to VR I have always been on 45 fps in AC utilizing Oculus ASW to keep the game playable. Never thought about optimizing the game because it was usable for me, and I was assuming VR just required loads of performance. So I simply lowered the graphics settings a bit, and then just drove.

Recently I have had frequent but random frame drops (to single digit FPS). I found turning off "automatic save replay" solved the issue, but in the process of troubleshooting, I accidentally lost my Python apps settings when using CM, and interestingly I had a huge increase in performance. This caught my attention and I started to trying to find out which app is consuming the most of my performance.

I am still in the tedious process of turning individual apps on/off, but it seems that it is not a particular app that is eating performance. For example 3D map eats a couple of frames, pitboard eats a bit more, acti eats a couple more, etc. Do you guys know if there is an easy way to do this process? Is there a way to pinpoint the app that is consuming the most performance?

Another interesting finding was by enabling CSP I get better framerates. I am guessing that some optimization settings in CSP makes the post-processing run more efficiently.

Just wanna share my experience. Now if I turn all apps off I can even run high res shadows and many other eye candies. If anyone has similar issues, it might be some Python apps that are eating the performance.

 

Found a solution myself. CSP has an app called Python debug and it displays the time each app uses to update value and display content. Very useful to figure out which apps are killing the performance.

Too bad the most demanding apps include RSRlivetiming, sim hub, and crewchief, but I don't wanna race without them.
