VRay RT With AMD HD7000 opencl compilation times ?
show user profile  FX
Anyone had experience with Vray RT and AMD cards ?

Fired off VRay Using Open CL, memory is at 85%, CPU is at 60%, somethings going on but after 20 mins i still just see "waiting for image data".

Is the compilation thing a one off ? seems to be taking far too long.

Core i5 and 8gigs of memory, gfx card is AMD Radeon HD 7600M, catalyst version 13.4.

the only anomaly I see is "cl_nv_compiler_options extension not found."

I gave up on this, vrayrt server crashes when compilation is finished, and gives be a black screen with any attempt to run it again.

I read the internet and the consensus seems to be VRay RT openCL simply doesn't work with AMD cards, bar a few exceptions and for people who don't mind spending half a day installing legacy drivers until they find one that works.
