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.
EXPreview.com website has published detailed pics of EVGA GTX 275 CO-OP PhysX – card with exceptional design, which combines two different GPU, G200 (GTX 275) and G92 (GTS 250), on one PCB.
55nm GT200b graphics-rendering chip (left one on a pic below) operates at a 633MHz core, 1296MHz shaders and has 896MB of GDDR3 memory, running at 2268MHz. 55nm G92b chip (right one), fully dedicated to PhysX processing, runs at a 738MHz core, 1836MHz shaders, and has 384MB of 2200MHz GDDR3 memory.
Cooling system consist of two heatsinks with heatpipes, fan in the middle.
Question “How Ageia PhysX PPU can handle newest GPU PhysX titles ?” is still interesting for some people, ATI owners for example. NinjaLane has published PhysX Performance Tests – The way games should be played article, that includes benchmarks of old Ageia PhysX PPU card along with Nvidia GPUs.
While PPU is still good at Unreal Tournament 3 and Mirror’s Edge, it has insufficient power to run latest titles like Batman Arkham Asylum with smooth framerate.

EVGA GTX 275 CO-OP PhysX edition graphics solution was announced recently. As predicted, mysterious card turns out to be GTX 275 dedicated for graphics and GTS 250 dedicated for PhysX on single PCB.
|Core Clock Speed||633+738MHz|
|Memory Clock Speed||2268+2200MHz|
|Shader Clock Speed||1296+1836MHz|
Recommended price is 349$.
Update: some pictures from Launch Event
Following Geeks3D report on that recent driver update disables PhysX hardware acceleration not only for Nvidia GPUs, but for Ageia PPUs as well (if non-Nvidia graphics card is present in the system) we’ve desided to perform small investigation.
Test methodology is simple enough: we’ll use certain sample from PhysX SDK 2.8.1 Build 13 to identify if Ageia PPU is working and initializing properly with different PhysX drivers on several systems with Nvidia and ATI GPUs.
Used PhysX System Software – 8.09.04 (last one with direct PPU support) and newest 9.09.0814 installed above 8.09.04 (PPU won’t be recognised on pure 9.09.0814 drivers)
GeForce System #1 – GTX275 + Ageia PPU
PhysX driver 8.09.04 PhysX driver 9.09.0814
GeForce System #2 – GTX295 + Ageia PPU (thanks to JeGX from Geeks3d)
PhysX driver 9.09.0814
As you can see, in both cases Ageia PPU was recognised properly by the system, and hardware acceleration is working too (test applications indicates that both scene and cloth simulations are running in hardware)
What will happen if we’ll try same scenario, but now with ATI GPU installed in the system ?
