New GPU Usage Policy in 5.3?

Recommended Posts

Hey,

is there something I missed.

Finished my upgrade (clean install) to 5.3 HF1 today and see, that my GPU is always at a 100% load.

Does anybody know something?

That wasnt the case in 5.2 for me :-/

 

Cheers

Bernd

28%-35% here with 2080TI. Some spikes ere and there but nice and calm. CPU also ok and I left default on 10700K. so far so good after initial flight CTD (not sure what happened). Other than that so far best performance LM ever made. So, few more flights to see if anything else is missing (except ChasePlane for now).

Have you updated your video drivers lately? I had the same problem running the newest Nvidia drivers. I downgraded to the 471.96 drivers and am back to normal usage rates (30-70%).

Cleared shaders?

Nope, everything same setup as in 5.2. Same settings same nvidia Settings.

Shader cleared. I had the same "problem" in the past moving from 5.1 to 5.2 too, but cant remember what fixed it :D haha

Isn't a maxed out GPU the goal? Meaning P3D is taking full advantage of your GPU's capacity to deliver the best performance your hardware can give you? That was an issue with P3D in earlier versions when it wasted potential by neglecting much of the GPU. Video games these days are designed to take as much out of the GPU as possible. Otherwise it's wasted potential and worse performance.

The goal is to have sufficient overhead and margin to maintain a desired FPS in situations that are very demanding on the GPU (lighting effects, AA, high resolution, shadows, etc.).

If you are in a situation where you are CPU limited (complex airliners and scenery) or when you limit the FPS to below what you get at unlimited FPS, your GPU will have less work to do, so why should it maximize its power?  That would only generate redundant heat and consume more electric power (and shorten the lifespan).

What I mean isn't that the GPU should be at 100% even if the workload doesn't necessitate a utilization that high, but that it should be utilized to its max when workload is high (GPU bound workload) so your GPU's full potential is used. Of course it shouldn't be at 100% when it has close to nothing to do, but that's not how I understood the thread.

I don't understand why you would be aiming to have your GPU sitting comfortably at no more than 30%. I would assume just about any scenario in P3D that involves higher settings and several addons would lead to a much higher utilization than that, so obviously you would want it to work a lot rather than chill along to give you better performance. A lot in P3D these days is GPU bound in contrast to early versions, so if I saw my GPU at around 20 to 30% in a 'normal' scenario with higher settings and a couple of addons I would be worried.
