I'm trying to increase my framerate on World of Warcraft, and I'm not sure if this will help but it should in theory. I'm not even sure if I'm right in my assumption that it's currently non-optimal.
nvidia-settings reports the full 1024MB of onboard video memory from my 420GT, but lspci reports three separate figures which don't even add up to 256MB:
01:00.0 VGA compatible controller: nVidia Corporation Device 0de1 (rev a1) (prog-if 00 [VGA controller])
Subsystem: ZOTAC International (MCO) Ltd. Device 1167
Flags: bus master, fast devsel, latency 0, IRQ 16
Memory at ee000000 (32-bit, non-prefetchable) [size=16M]
Memory at e0000000 (64-bit, prefetchable) [size=128M]
Memory at e8000000 (64-bit, prefetchable) [size=32M]
I/O ports at dc80 [size=128]
[virtual] Expansion ROM at efe00000 [disabled] [size=512K]
Capabilities: <access denied>
Kernel driver in use: nvidia
Kernel modules: nvidia-current, nouveau, nvidiafb
Now, I don't know which to trust, is all the video memory being detected or just the pittance that lspci reports?
To my mind, more graphics memory means you can store more graphical code and data closer to the gpu resulting in faster framerates, right?
So, is there any way to correct the problem (if it exists) and/or increase the performance of the card?
Thanks in advance.
