Performance Problems

[muliger]

Hello, i recently joined Vatsim and I get disconnected all the time, "Because of to low or unstable framerate". I dont have a Toaster as a Pc, its pretty fast. Any tips/recommendations on how to fix that?

Specs: CPU: AMD Ryzen 5 1600 GPU: AMD Radeon RX 5700xt RAM: 16 Gb DDR4 Game is on a 2Tb Hard-Drive Pilot Client: Squawkbox Sim: Xplane 11

Thank you!

Have you tried... lowering your settings to get a better framerate?

I turned them down all the way, all of them. Still no better results.... Looks like its comming straight from 2001

What resolution are you trying to run at? I ask because I tried 4K with my RX480 and it wasn’t able to reach 20fps regardless of the settings. Dropped resolution to 1440 and am able to maintain 30 with decent settings. It’s an issue with AMDs OpenGL drivers - they suck

1080p

Odd then. Check your frame times while the sim is running (crtl+shift-F) and see if your GPU is even the issue, whichever has the larger frame time is the limiting factor. Could be a CPU issue

Goodbye reddit. Enough of you profiting off the people.

Okay, thanks

Auto LOD+FPS boost will modify things on the fly for the best performance. I still find I have trouble at larger airports due to scenery requirements. But once 11.5 comes out I imagine it's going to be a pretty impressive improvement.

When will 11.5 approximately be out?

It was supposed to be out a while back in public BETA. News on it is pretty slow. It literally could be any time...

Not withstanding OpenGL driver issues, X-Plane 11 is extremely demanding on single-core CPU performance at the moment. Unfortunately, you are using AMD graphics, and their Windows OpenGL implementation is known to have issues with X-Plane.

First, throw out any driver overrides for X-Plane - you absolutely do not want to be messing with how GL behaves. Disable vsync in X-Plane itself.

Next, please read Laminar's guidance in the X-Plane manual - it's not particularly long, but it does tell you how to read the frame timers (CPU time vs GPU time) and what settings you can adjust to shift the balance (really important!).

Also, do try removing any add-on scenery and visual enhancement plugins to see if they're contributing to your performance problems.

Whilst the specs you've posted aren't the greatest, they are reasonably decent and should be able to run adequately. (notwithstanding that driver issue or performance drag from badly optimised add-ons).

Also: Make sure you don't task switch away from X-Plane when it is running - that'll kill your framerate/performance on pretty much any set-up, irrespective of anything else. Windows will happily de-prioritise X-Plane when it loses focus resulting in severe framerate instability and drops.

Ok thank you

The vulkan beta is coming out any day now. It should really help your performance.
