In 0.16 WaiTex used ~2GB of vram. Making the textures any larger would require ~8GB of vram. I don't have a graphics card with 8GB of vram. I know 0.17 did some vram savings so i will have to look into the usage again. I have other reasons for upgrading besides this so i may do this soon.
Mainly allowing me to game at higher settings but some programs i want to use simply doesn't support my graphics card. Need to upgrade to use them. It's not much of a problem as there is alternatives but it's a nice to have. Having a gpu that doesn't sound like a jet engine would also be nice :)
Ah, actually that was my bad, i misread what you said, i thought you were still talking about game textures hence why i was wondering what else would there be to upgrade if not the raw resolution :) Good luck in getting that new gpu though!
