Compiz using GPU or CPU???
Hi,
I'm using the latest (3.4a) version of Sabayon Linux. It's great. The graphics and design are amazing. It comes pre-installed with loads of goodies. It uses NVIDIA binary drivers out of the box. Anyways, the problem is that compiz runs slower/jerkier than with other distros. Effects get stuck midway (such as opening/closing windows). The OpenGL screensavers seem to run slower than normal. I tried re-installing the NVIDIA binary drivers manually, but no improvement. I have a GeForce 8500GT graphic card. How can I be 100% sure my system is using the GPU to its fullest to render? Is it possible that rendering is taking place in software? My CPU is Core2Duo 6350. I see the NVIDIA Logo when X starts. My xorg.conf file looks like this (entries unrelated to graphics are not included): Section "Module" Load "dbe" Load "i2c" Load "glx" Load "ddc" Load "type1" Load "freetype" Load "extmod" Load "synaptics" Load "vbe" # Load "dri" EndSection Section "Monitor" Identifier "Generic Monitor" #Option "DPMS" VertRefresh 43 - 60 HorizSync 28 - 80 EndSection Section "Device" Identifier "nVidia" Driver "nvidia" # do not remove vesa #Option "RenderAccel" "on" #Option "XAANoOffscreenPixmaps" #Option "BusType" "PCI" #Option "ColorTiling" "on" #Option "EnablePageFlip" "on" EndSection Section "Screen" # The Identifier, Device and Monitor lines must be present Identifier "Screen 1" Device "nVidia" Monitor "Generic Monitor" #Option "AddARGBGLXVisuals" "true" # The favoured Depth and/or Bpp may be specified here DefaultDepth 24 SubSection "Display" Depth 8 ViewPort 0 0 #Modes "1024x768" "800x600" "640x480" EndSubsection SubSection "Display" Depth 16 ViewPort 0 0 #Modes "1024x768" "800x600" "640x480" EndSubsection SubSection "Display" Depth 24 ViewPort 0 0 #Modes "1024x768" "800x600" "640x480" EndSubsection EndSection Section "DRI" Mode 0666 EndSection Section "Extensions" #Option "Composite" "Enable" EndSection |
You have a lot of options like Render Acceleration commented (#) out. Perhaps enabling some will give you better perfomance. Naturally make a copy of your xorg.conf before doing any changes, just in case things go wrong.
