Whatever you want it to be.

I was having a quick flight yesterday evening, so about 13hrs ago and the performance was terrible for me, I was struggling to get 30 fps at times at Pilot Plus EGGD - frames came back a little after take off.

 

I'm 100% certain a lot of the performance issues since launch have been Server related.

Folks should really only test and evaluate performance with no live weather (pick a preset like clear sky), no AI traffic, no scenery mods, and cache turned on, and having conducted a flight in that area already to cache the terrain data… in the same plane. Otherwise, all these various factors could absolutely be impacting your performance making comparisons between today and yesterday, or this release and that release, or this hardware and that hardware, completely useless.

You only have to compare with a discovery flight to see the difference- it’s not a big secret

I was just looking at some things.... was on approach into KORD recently and the textures had not fully rendered even on short final. Had me question what was going on. 

I looked through the nvidia overlay and CPU usage was about 20% whereas GPU was 80%-90%. 

What should this be normally?

i9-12900k / RTX 3080ti

I find that the key to smoothness is at whatever frame rate you choose to run at make sure that in the developer fps window your GPU timing is always higher than your main thread timing (always GPU limited). If your constantly main thread limited you have a much higher chance of stutters. I have found that with my PC running high to ultra settings at 60 fps in the PMDG 737 my CPU will only show average use of 25% - 35% and my 3090 will be around 75% - 80%

In the Fenix A320 however  I tend to lock at 30fps but every setting is maxed out and I even push the render display to 130 to keep the load on the GPU higher (around 30ms) but it’s very fluid and smooth even though it’s only 30 fps

Agreed, a slight preference towards GPU or just balanced with neither GPU or CPU waiting excessively long for the other, seems optimal.

If your limited by main thread increase GPU hungry options. If your limited by GPU increase settings that rely on CPU.

Is there a breakdown somewhere of which settings hammer the CPU vs GPU?

 

For CPU the Terrain and Object LODs are a big hit,

For GPU the Render Scaling is the biggest.

This is an older thread that goes through every setting in detail but it has not been updated since SU5 and we are currently on SU9 .  Most things will not have changed much.

Photogrammetry always makes my CPU the bottleneck.
