Increase texture cache @ 4 GiB DRAM for higher VRAM cards (#8)

Browse Source 
This increases the texture cache when 4 GiB DRAM is selected in the System settings for GPUs with 6 GiB VRAM or more.

Improves performance when using high-resolution mods @ 4 GIB DRAM and may help with other texture cache scenarios ; i.e., a lot of high-res mods require increasing to 6 GiB DRAM or more, but with this change, you *may* be able to get away with 4 GiB DRAM in some cases.
