Try as I might, I cannot get my GeForce 3 under OS X to render a 2048x2048 texture. Is there a hardware (or driver) limit I’m unaware of? I have shedloads of texture memory, under Cocoa (Interface Builder) I’ve switched off the depth buffer, stencil buffer and accumulation buffer in the hope of reclaiming a few Mbytes, and I’m only running a 720x576 window, so I definitely have enough RAM to do this.
