Hi, i bought a new GPU ATI R9 270x, i was surprised to see that Adobe After Effects use barely 10% of the GPU, previously i had Crossfire 2x 7770 HD, Adobe used second GPU at 100% so the problem is not Adobe not being able to use GPU, it's something else.

How can i make Adobe After Effects CS 6 use more of my strong GPU? If i put a second graphic card will it start using the second GPU at 100% even if not Crossfired?

My computer specifications:
CPU: Intel Core2 Quad CPU Q6600 @ 2.40GHz
Motherboard: Gigabyte EP35-DS4
RAM: 2x 2GB 400Mhz(Dual channel) 1x 2GB 800Mhz
GPU: ATI R9 270x
PSU: Corsair Gaming Series™ GS800 — 80 PLUS 800 Watts
Hard Drive: Toshiba 7200 RPM performance, 6 Gb/s SATA Interface

CPU-Z validated specifications: http://valid.x86.fr/bu611w

Found an answer on Adobe Forum, appereantly Adobe After Effects CS6 is badly optimized for GPU use, expect for Ray-Tracing 3D where it support Nvidia cards only, here is a quote from a guy that helped me understand it.


GPU acceleration in Ae is so misunderstood. CUDA only accelerates one specific feature in Ae -- the ray-tracing renderer.

Everything else renders mainly on the CPU. A few effects (like Magic Bullet Looks, Video Copilot Optical Flares and Element 3D, GenArts Sapphire, and Mettle FreeForm and ShapeShifter Ae) are able to use GPU acceleration. Particular is not among them.
