Huge performance drop due to recent updates

[Zius]

Due to circumstances, I hadn't started DCS for about a month.

 

 

Now I had some free time, downloaded the last updates (open Beta) and started DCS.

 

 

One month ago, I had all settings on "high" and got decent FPS. Sometimes, e.g. with a lot of AI aircraft it could stutter a bit but mostly it was pretty smooth.

 

 

Now DCS just freezes when in the cockpit, then stays frozen for a couple of minutes and ends up with maybe 1 to 0.1 FPS.

 

 

When I put all settings on "low" it becomes more or less playable again but is still slower than in the past, as well as looking much worse.

 

 

I have already tried several things, like deleting the "fxo" and "metashader" folders, turning vsync on, etc, but no success so far...

I don't have that problem, so I guess it's something on your end.

 

 

 

Freezing when entering a mission points to a problem while loading textures. Could be the disk has a problem.

Or could it be that you're playing on a laptop and the game is somehow using the integrated graphic chip while it used the dedicated before?

The first error is:

 

 

2019-10-24 20:26:13.662 ERROR DX11BACKEND: DX device removed. Reason: 0x887A0020

 

 

 

Seems to be related to graphics card driver problem. I just downloaded new drivers from AMD. DCS loading screens seem to be a bit faster than before, but now DCS just plain crashes when loading the mission (final stage before entering the cockpit).

You DCS log says you are using "Intel® HD Graphics 4600"

 

this is below minimum spec, please ensure you are using your dedicated GPU for DCS

 

I know it sounds silly make sure your monitor is plugged into the correct GPU and not your motherboard :)

Actually the situation is back to normal now...

Thanks for the tip! I could not imagine I made such a stupid mistake but apparently I did it anyway...
