With vanilla Minecraft 1.7.10, my current rig can handle a 512x texture pack (Sphax's PureBDCraft), but if I try to use Optifine connected textures, run Minecraft 1.8, or add resource packs for mods, I get a StitcherException unless I use lower-resolution resource packs. I found out when I asked at the Minecraft forums that this is caused by the texture atlases going over the max texture size of my gpu, which is 16384x16384 (I have two GTX 780s). Since then, I have been wondering what graphics cards have higher max texture sizes, but that detail doesn't seem to be listed in the manufacturer specs. I haven't have much luck asking about this at another hardware site, so I thought I'd try here. Does anybody here know of graphics cards (available in the US) with max texture size of 32k x 32k or higher?
