What's Going On With My GPU?

Recommended Posts

When the sim first came out, I was hitting 60 fps easy, with my settings on High (with clouds on Ultra).

Then I added some liveries, and of course the FBW A320NX, and my frame rate started dropping.

I currently have it locked at 45 fps, never have more than 5 liveries in community folder at any time, and I struggle to maintain the 45 fps, sometimes dropping into the low 30's and on occasion the high 20's (flying into busy airports at night).

I have now noticed that my GPU is only being used on average 25%. With other games, I typically hit upper 90's even 100% on the GPU.

Any insight as what could be happening? Any recommendations?

Many thanks.

Have you locked the game at 30 fps? this causes GPU usage to go down significantly.

It is currently locked at 45 fps.

Is it better to Not lock it to any frame rate?

Not in my experience, I get smoother and stutter free gameplay at busy airports  when I lock at 30 fps, but my GPU usage get lower overall, about 60-65% locked and 95-100 unlocked.

Yes, I also think it is always better to lock the frame rates.

But I thought higher utilization on the GPU was better. That is why I am wondering why my utilization is so low.

Can't figure it out.

just had the same thing happen. was running just smooth at 60fps. now sitting at 20fps choppy display. FPS counter shows limited by GPU.

Try to Increase the graphics settings that have impact to the GPU.

I'll give that a try.

Thanks.

I think its the A320NX - I noticed a hit using this bird - try Asobo A320 and see what happens

Its not so much the frame rate (i'm sitting now at FL340 getting 40-42, with it locked at 45). What I'm wondering is why my GPU utilization is so low.

If your frame rate is locked where you want it but your gpu utilisation is low, surely that is a good thing? It shows you have some headroom for adjustment, and it isnt working your card too hard. 

Unlock your frame rates if you want to see 100 percent utilisation with lots of heat and noise! 😁

Is it possible that by locking the framerates it is making GPU utilization so low that the GPU is down clocking and causing further slowdowns?  

I've seen some people observe behavior like this over the past couple years as GPUs no longer run at fixed clocks in 3D mode.

That is also a possibility. I need to play around with things.

But I've never seen my GPU utilization so low in a game.

If you turn on the MSFS internal Developer Mode from the options menu and then turn on the MSFS FPS display, the display tells you what the limiting factor is (CPU threads for main and render, or GPU).

Cruising at high FLs with no ground details being rendered is not going to be taxing on the GPU in many cases.  It can easily flip from being GPU limited at altitude to CPU limited near the ground or near busy airports.
