We're going to increase the amount of memory used to cache WoW textures in your video card which will reduces your loading time and increases your fps in bloated places.
First you need to know how much RAM you have on your
video card
Run -> dxdiag -> Display tab (monitor in danish)
We're going to allocate half this value to textures caching meaning:
If you have a 1024MO card, allocate 512MO (write 536870912)
If you have a 512MO card, allocate 256MO (write 268435456)
If you have a 320MO card, allocate 160MO (write 167772160)
If you have a 256MO card, allocate 128MO (write 13421772
If you have a 128MO card, allocate 64MO (write 67108864)
If you have a 64MO card, allocate 32MO (write 33554432; BASE VALUE)
You can allocate more memory than this (never allocate more than 512MO) but if you overflow your video card, the system will use its own memory instead meaning any benefits will be lost.
The ingame command is /console texturecachesize XYZ
XYZ being the exact value in octet you want to allocate (you have to convert megaoctet value to octet like I already did).
Example: I have a 256MO video card, the command I'll be using is /console texturecachesize 134217728
NB:-You have to reboot the game for the change to take effect
-I'm not 100% sure of the vocaburaly I used but I'm sure some IT nerd will correct me if I'm wrong somewhere
-Go back to the base value if you have any problem (/console texturecachesize 33554432)
-The command is being changed to /console gxtexturecachesize ABC for 3.3, ABC being this time the value in megaoctet directly (no longer need to convert)
Hope this helps.
