In minimum graphics setup, i only archive 20 to 25 FPS

I use X-Plane 10.45 with Steam - but have this problem vor 1,5 years now.

In this 1,5 years i have used Win 7,8 and now 10


AMD FX 8320

AMD R9 270 2 GB (16.1.1)

16 GB RAM (since 1 month) - 8 before

250 GB SSD

Why is X-Plane running sooooo slowly?

I was very patiently in the past, waiting for patches. Its Laminar Research not EA. But now - especialy after upgrading RAM I slowly getting angry...

I testet with no Add Ons


CPU usage 17%, GPU usage 60%, 1.6 GB VRAM usage, 6.4 GB RAM usage  (even if extreme graphics and the Carenado Baron)

Sorry for the maybe bad english - a lot of time left since school.

Hope you can help or even fix the bug.

Alright I am more of an Intel person but one way to find out your system capability is put all the rendering settings at the lowest option then start increasing one setting at a time till your computer can't handle it anymore.

My specs for comparison

MSI Z-87 G-41 Motherboard

GTX 970 4 gb VRAM

Intel i7 4770k @3.5ghz

16 gb RAM

I get 30+ fps with a 4 year old CPU and motherboard

HDR and clouds and cars and buildings are GPU killers so make sure those are turned down as well as texture resolution. I have that at very high.

I have all render settings to lowest options and never more then 30 fps. Exept there is not one single cloud in the sky and no terrain to render - then 40

Have you set the frame rate to "does not lock"?

Since i am not part of Laminar, soon someone will respond.

Are there errors in your log text?

Try reseting the sim by deleting the preferences files inside the folder

Hi Mathias,

Your system does seem to meet the minimum specs for X-Plane. It does not meet the recommended specs, so I am not surprised you cannot "max" out your settings. I would be interested to see your log.txt as well as a screenshot of your rendering settings.

Have you tried using the rendering presets that were introduced in 10.40? There are a lot of separate things you could tweak in the rendering settings screen and maybe or maybe not see much of a change. You should see a big difference between the presets. Make sure you restart X-Plane after every preset to actually see all the effects.
