[SOLVED] Catalyst performs poorly and corrupts shutdown messages

Kopkins · 2014-11-07 21:29:01

Hey guys,

I'm running just an AMD A10-5750M APU and I just switched to the catalyst driver and I'm getting worse performance than with the radeon driver, about 70%.

However, using fglrx, my CPU can clock up to 3.5 GHz where before it was only up to 2.5GHz. Direct rendering is enabled, and it runs glxgears and fgl_glxgears much faster than with radeon (about twice the fps).

Additionaly, I'm playing the games through steam which seems to degrade performance. When I run fgl_glxgears normally (no compositor, just after x starts) I get about 1200-1400 fps, then when I lauch steam (even without launching a game) I can only get about 600 fps. In game (CSGO) I can get only about 35-55 fps, where with radeon I could get about 55-75.

Everything seems like it should be running faster but with steam everything is degraded. When I first installed catalyst, I was able to get about 100-110 fps running CSGO on the same settings, but ever since then I can't.

Also, when I shutdown now from within X, the shutdown messages are all corrupted and I can't read them at all. This doesn't happen when I shutdown from a tty. I made sure that I have nomodeset as a kernel parameter, but I don't know what else to do and haven't found anything from searching either of these issues.

Here is my xorg.conf:

Section "ServerLayout"
	Identifier     "aticonfig Layout"
	Screen      0  "aticonfig-Screen[0]-0" 0 0
EndSection

Section "Module"
EndSection

Section "Monitor"
	Identifier   "aticonfig-Monitor[0]-0"
	Option	    "VendorName" "ATI Proprietary Driver"
	Option	    "ModelName" "Generic Autodetecting Monitor"
	Option	    "DPMS" "true"
EndSection

Section "Device"
	Identifier  "aticonfig-Device[0]-0"
	Driver      "fglrx"
	BusID       "PCI:0:1:0"
EndSection

	Device     "aticonfig-Device[0]-0"
	Monitor    "aticonfig-Monitor[0]-0"
	DefaultDepth     24
	SubSection "Display"
		Viewport   0 0

	EndSubSection
EndSection

EndSection

OK, do you actually need nomodeset in the kernel parameters for your card or not? I stopped using nomodeset after Catalyst 13.10 because I didn't need it for my AMD A4-3305M APU with AMD Radeon 6480G Graphics after that version.

Thanks clfarron, I took of nomodeset and that fixed my performance issues. I'm back getting between 55 and 100 which is totally acceptable.

The shutdown messages are still corrupted though.

Well that's good

Chances are, I won't know how to deal with this, but I think for others that may, how are they corrupted? Tearing, fonts drawn badly, something else which requires a photo to describe?

A picture is probably best to describe.

This only happens when I shutdown from within X, for example within a terminal, but if I shutdown from a tty while x is running in another its fine.

Oh... This. I randomly get this once in a while when I shutdown from X as well. As far as I'm aware, it's not caused me any issues to my hardware or installation, so I never looked into it.

Yeah it doesn't seem to have caused any issues so far besides obfuscating my shutdown messages. It's not too hard to exit my openbox session before shutting down anyway.

Thanks for you help clfarron
