Many of you know that so called Hybrid PhysX setups (using ATI GPU for graphics and Nvidia GPU for PhysX – in one system) are officially banned by Nvidia. Unofficially – available through GenL PhysX mod. However, all this hacking and patching isn’t appropriate for certain users, not to mention that Nvidia can find a way to block Hybrids completely one day.

New Lucid Hydra, technology that can split graphics rendering even between  ATI and Nvidia GPUs in Multi-GPU setups, was rumored as compromising solution for Hybrid PhysX problem. (can’t say we believed in that).

Unfortunatelly, recent tests of MSI Big Bang Fuzion, first motherboard with Hydra Engine inside, have shown finally – No. It’s not working this way.

According to Big Bang Fuzion review by GURU 3D

What if you want to enjoy PhysX in X-mode? – well you can’t, as the minute the NVIDIA driver sees an ATI card, it will disable it.

Batman Arkham Asylum benchmarks from Big Bang overview by tomshardware.com are showing that there is no benefit from ATI+NV combo setup

Thus, PhysX mod by GenL is the only way currently to get Hybrid PhysX setup working.
