Ideal GPU usage percentage?

Recommended Posts

According to Rob’s P3D guide all shadows are GPU bound. So little to none CPU bound.

Where is that guide at?

If your monitor is capable of 30Hz use NCP to set it to that and the results are a very smooth sim. If not then the 1/2 refresh rate is the alternative.

@sho69607, is your monitor capable of 30Hz?

No it only goes down to 60hz, so I am doing exactly that. Works fine unless I drop below 30fps then I get screen tearing and stutters. As a side note, every time I open the atc window there is brief stuttering. Not sure if this is related to the refresh rate or something else.

How unfortunate. The very first heading in entitled "Forward". Needs to be edited, surely it is meant to be "Foreword". Spell checker got the upper hand on proof reader.   Excellent read though. Lots of stuff I didn't even know about. Will try the suggestions out soon.

When researching for monitors it's always worth checking the lowest refresh rate they support. 30Hz does make for an easier solution. Can't answer your other questions - sorry.

I used to set my outside monitors (3x 27inch) to 30Hz for many years - gave me the most fluid and stutter free picture. But since a few month i tried 60hz (native), in P3D set Frames to Unlimited and Nvidia Inspector to 1/2 Refresh Rate (like in former times when i used FSX) ... it is even much more smoother now 🙂 Try it, perhaps it helps you to get rid of your stutters.

Markus,

I did try it but found lots of micro-stutters even in remote places like default Alice Springs in Australia. Using 30Hz with VSync is the smoothest I've seen.

I use FSUIPC to adjust Ai traffic to maintain 30 so even at 95% of airports I still get 30. Heathrow and a few other major ones are the exception of course.

I think it depends on PC and, of course, on the setup in special. In my case it was really fluid with 30Hz, but when i changed to 60Hz especially in the edges of my monitors i even got rid of the few micro stutters ... so, glad to hear 30Hz work on your system!

Ended up picking up a 2080ti and let’s just saying I’m not disappointed 😃. Wanted the 3080, but with gpu prices expected to go up further, I don’t know how much of a bargain that card will continue to be. The only option right now is paying out the nose for one on EBay. Also VRAM is another concern. My #1 would’ve been the 3090, but that is out of my budget right now unfortunately.

Unless you're limiting your FPS or system performance, or bottlenecked by your CPU, your GPU usage should always be high (90-100%). If it's not, that's because the sim/game is "broken". That's the case for P3D. 

I have a 5700XT + i7 9700F and GPU usage is all over the palce. Sometimes I get good framerates, sometimes terrible ones; GPU usage varies from 15-99%, it's just random. 

For comparison, with MFS my GPU is at 99% all the time, which is great, and the performance is way better than P3Dv5.
