[SOLVED] FGLRX driver limited to 60 FPS

[Orion]

Hello, I installed an ATI proprietary Driver following this wiki article http://docs.salixos.org/wiki/How_to_Install_ATI_Driver and everything works fine except for some reason it's limited to a low frame rate of 60 fps despite the fact that direct rendering is on.

Here is an output of glxinfo | grep render

Code: Select all

direct rendering: Yes
OpenGL renderer string: AMD Radeon HD 8570D
    GL_ARB_compute_shader, GL_ARB_conditional_render_inverted, 
    GL_KTX_buffer_region, GL_NV_blend_square, GL_NV_conditional_render, 
    GL_ARB_conditional_render_inverted, GL_ARB_conservative_depth, 
    GL_KTX_buffer_region, GL_NV_blend_square, GL_NV_conditional_render, 

Here is the result of vblank_mode=0 glxgears

Code: Select all

orion[~]$ vblank_mode=0 glxgears

300 frames in 5.0 seconds = 59.881 FPS
300 frames in 5.0 seconds = 59.881 FPS

And this is my xorg.conf

Code: Select all

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"
	Option	    "SwapbuffersWait" "false"
	BusID       "PCI:0:1:0"
EndSection

Section "Screen"
	Identifier "aticonfig-Screen[0]-0"
	Device     "aticonfig-Device[0]-0"
	Monitor    "aticonfig-Monitor[0]-0"
	DefaultDepth     24
	SubSection "Display"
		Viewport   0 0
		Depth     24
	EndSubSection
EndSection

Normally, the benchmarks of proprietary drivers with 3D acceleration would show an average FPS rate in the hundreds, thousands even. How could I increase my FPS rate?

Solved this issue by simply reinstalling the FGLRX driver by following this guideline http://docs.salixos.org/wiki/How_to_Ins ... he_Drivers Since the driver is now working properly, performance is now much greater as illustrated by glxgears:

Code: Select all

46303 frames in 5.0 seconds = 9260.593 FPS
47346 frames in 5.0 seconds = 9469.191 FPS
47337 frames in 5.0 seconds = 9467.288 FPS
47307 frames in 5.0 seconds = 9461.226 FPS
47349 frames in 5.0 seconds = 9469.672 FPS
47297 frames in 5.0 seconds = 9459.385 FPS
47352 frames in 5.0 seconds = 9470.377 FPS
47294 frames in 5.0 seconds = 9458.777 FPS
47346 frames in 5.0 seconds = 9469.137 FPS
47323 frames in 5.0 seconds = 9464.480 FPS
47330 frames in 5.0 seconds = 9465.822 FPS

I'm oblivious as to what directly caused the issue, although simply reinstalling the driver did the trick nonetheless.
