Whenever I start a flight my gpu usage is at an appropriate amount, then slowly goes down throughout, causing my FPS to drop to 20 fps and under. Not totally unplayable just suuuper annoying and seems like it happens for no reason at all. Why’s it not using all my GPU? Totally annoyed by this issue …

I have the same issue: during the initial cut scene when entering the runway the frames and GPU utilization are ok (still lower as the used to were prior SU7) but when actually starting the flight the utilization plummets down to about 50 to 60%. During flight sometimes it jumps up to 70 - 100% for …

I would assume it’s for the obvious reasons that some things in the sim are CPU bound and some GPU bound. If, at any particular part of the flight, the sim is primarily drawing on the CPU then GPU usage will drop as it doesn’t have as much to do. This applies to any game whether it’s COD or XPlane o…

Not mods happens with everything. Not everyone has the luxury of having a high-end rig like yours. Stop being smart. And as seen in this thread and multiple others, even those with high-end rigs run into the same problem, mods or no mods.

It’s not the player’s jobs to do the testing and figure it out for themselves, it’s the devs jobs to properly optimize the software. Also, CPU usage is low as well.

For me sim is probably at it’s best in terms of performance. I used to get stutters on final because the AI Planes were generated, right now even that is gone. I get quite decent performance in big airports like KLAX KSFO LTFM etc. Of course I don’t know why it changes too much from user to user. M…

Well I mean, you do have a monster of a rig… so that’s probably why.

Trust me I used to have quite a lot of stutters and stopped playing the sim for a while. But I set my vsync to 30 maybe that may be doing an effect :thinking:

Mines on 30 too. Would you have any idea what your GPU usage is during a flight? Also what planes do you usually fly.

I’ll try to check it tonight and will try to let you know. For now what I can say is that I play the game on ultra settings except LOD is set to 200, and I fly with either FBW A32NX or Headwind A330-900 Neo. Even FBW gives me a decent performance that’s why I am very happy with the current version.…

Interesting thanks for sharing. I’m stuck flying short hops in the CRJ for now because the FPS drop on long flights in the a32x are killing me. Less than medium settings too. Maybe it’s a RAM thing because I only have 16gb.

Performance degradation, gpu under 50% usage
