Hydrax Efficiency

For anyone who reads these forums, what kind of frame rates on what kind of render systems to you get for Hydrax? I can't believe how low mine are. I'm getting between 20 and 35 fps but I have a very powerful GPU. I use a Radeon HD 5770 and it plays Crysis at those frame rates. Anyone know what could be going on? I'm running Linux at the moment and I use the ATI Proprietary drivers for the card. I am going to test it under the DX10+DX11 renderers for Windows now.

Im only getting about 10 - 15 FPS with a GeForce 8200M G running on Linux

Hydrax is extrememly CPU intensive, its is actually fairly gentle on the GPU!

Well my CPU isnt that great either AMD Sempron SI-42
