I am seriously considering getting a saphire 7970 vapor X 6gb(due to the amazing work that Dade is doing in integrating SLG3 into Lux), but if there is a texture limit then there may not be any point.

The limitations are imposed by the small amount of ram that GPUs have, usually 1GB or 2GB. When a program like SLG or Octane use the GPU exclusively the GPU RAM is used for both the geometry and the texture and texture take a lot of RAM very quickly. Having said so, the new SLG3 is improving the texture management quite a bit.

Anyway, I am partial to AMD GPUs as well. I don't know the model that you quoted but my 5870 works very well.

Cheers.

 

Hi Paolo,

Understood, but on the Nvidia cards you can only load so many textures into VRAM, i.e. 64 or 74, IIRC, on the 5 series cards, even if you have VRAM left over, after using all of the available 'Texture Slots'.

Its an additional limitation with the nvidia cards, and I wondered if the AMD cards had a similar limitation, with regards to the number of textures you can load into their VRAM, irrespective of the amount of VRAM available. if not....happy days.

S.K.
