Hi, Does anyone know of a benchmarking tool that can be run in both Linux and then in a Windows VM that measures 2D acceleration? I'm just curious about what sort of differences I'll see on this machine for native Linux vs a VM running on the same machine.
I'm currently using a Radeon 5770 (I think...) with the Open Source drivers. glxgears gives me about 1100 FPS the way it's set up right now. If I resize the terminal that glxgears is running in (by grabbing the lower right corner and just constantly moving it around for a minute) I see the FPS drop to maybe 450. Watching in top it looks like X uses no CPU until I start resizing the terminal and then 1 CPU out of 12 jumps to 100% while I do that. My Windows VMs on this machine use low CPU (<5% running stock trading programs) until I start changing window sizes inside the VM at which time they jump to 80% or 90% so it's similar I think. However I don't know the FPS in Windows. I'd like to understand if that's something I could improve by changing my X setup or by using a different video card. The above numbers came from VMware Player. I've got VirtualBox also but haven't tested it yet under load. xorg.conf below if anyone sees anything that could be improved. m...@c2stable ~ $ glxinfo | grep rendering direct rendering: Yes m...@c2stable ~ $ Thanks, Mark m...@c2stable ~ $ cat /etc/X11/xorg.conf Section "Files" ModulePath "/usr/lib64/xorg/modules" FontPath "/usr/share/fonts/misc/" FontPath "/usr/share/fonts/TTF/" FontPath "/usr/share/fonts/OTF" FontPath "/usr/share/fonts/Type1/" FontPath "/usr/share/fonts/100dpi/" FontPath "/usr/share/fonts/75dpi/" EndSection Section "Module" Load "extmod" Load "glx" Load "dri" EndSection Section "DRI" Mode 0666 EndSection Section "InputDevice" Identifier "Keyboard0" Driver "keyboard" EndSection Section "InputDevice" Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/input/mice" Option "ZAxisMapping" "4 5 6 7" EndSection Section "Extensions" Option "Composite" "Enable" EndSection Section "Device" Identifier "Card0" Driver "radeon" #Option "monitor-VGA1" "Samsung2333" EndSection Section "Monitor" Identifier "Samsung2333" VendorName "Samsung" ModelName "2333" Option "PreferredMode" "1920x1080" HorizSync 30-75 VertRefresh 56-61 EndSection Section "Screen" Identifier "Screen0" Device "Card0" Monitor "Samsung2333" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 8 Modes "1920x1080" EndSubSection SubSection "Display" Viewport 0 0 Depth 16 Modes "1920x1080" EndSubSection SubSection "Display" Viewport 0 0 Depth 24 Modes "1920x1080" EndSubSection EndSection Section "ServerLayout" Identifier "cruncher" Screen 0 "Screen0" 0 0 InputDevice "Mouse0" "CorePointer" InputDevice "Keyboard0" "CoreKeyboard" EndSection m...@c2stable ~ $
