Maya LT 2015 or Blender 2.71?

There is an environment variable you can set to turn on GPU support for AMD cards. It’s not enabled by default for a few reasons, but if you’ve got a hefty AMD card, it’s definitely worth enabling. I’ve been using it with dual FirePro GPUs for a while, and I’ve only had one Blender file where it couldn’t compile the kernel and use the GPU for both in-window rendering and final rendering. I set the compute device to use both GPUs and all CPU cores, and it screams. Makes a huge difference in day-to-day Blender use for me.

To turn Cycles rendering on for AMD cards
:
[FONT=Courier New]setenv CYCLES_OPENCL_TEST all

Be aware, though, if you have an AMD or consumer grade GPU, it may simply not be capable of rendering most Cycles scenes. I have no idea how the HD7750 will handle it, but it can’t hurt to try it out.

Daaaaang, where was this a year and a half ago haha. I remember researching cycles and ATI cards and most people said the reason why it never worked (I forgot which version it was after) was because ATI changed something in their drivers making it harder for the Blender devs to include it.

If I ever go back to my 7870 I will try this out. Thanks for the tip!
