GTX275 + GTS 250 PhysX Co-Op

[becco]

This ain't an EVGA GTX275 PhysX Co-Op Edition but GeForce GTX275 by Sparkle and GeForce GTS250 by Asus in cooperation to render Graphic and PhysX.

(ups, wrong image)



So basically what i've done is just installed GTS250 into secondary PCI-Express on my Asus P5Q Pro (P45) motherboard which do not have SLI support. As you can see I even didn't plug any SLI bridge on them.

How about DVI dummy, or another 2nd display monitor for 2nd GPU? No, i don't need that. In this picture we can see that there's only one DVI cable plugged on primary GPU (GTX275).



System Setup
- PSU: FSP Epsilon 700W
- Motherboard: ASUS P5Q Pro
- Processor: Intel Q9550 @3.6GHz
- RAM: 2x2GB G.Skill @1130MHz 5-5-5-15
- Display: BenQ G2410HD 24"
- OS: Windows 7 Home Premium 64bit
- VGA driver: Forceware 191.07
- Primary GPU: Sparkle GTX275
- Secondary GPU (as PhysX): ASUS GTS250

After I measured that everything was right then I press power button of my PC. Forceware 191.07 is already installed on my previous setup with GTX275. Let's Forceware do the rest to do initialization of secondary GPU.
... and it's done!



Next for some PhysX benchmarks ...

Batman Arkham Asylum


Setup:
1920x1080 8xAA
All highest possible
PhysX: High

*VSync: ON


GPU PhysX OFF: terrible
Min: 12fps, Max: 28fps, Average: 19fps



GPU PhysX: GTX275 alone
Min: 25fps, Max: 60fps, Average: 43fps



GTX275 + GTS250 PhysX dedicated
Min: 37fps, Max: 60fps, Average: 54fps





Star Tales PhysX Benchmark



Setup:
1920x1200 4xAA 16xAF
All highest possible



GPU PhysX OFF: terrible
Min: 9fps, Max: 96fps, Average: 19fps



GPU PhysX: GTX275 alone
Min: 17fps, Max: 588fps, Average: 39fps



GTX275 + GTS250 PhysX dedicated
Min: 22fps, Max: 482fps, Average: 53fps




Nvidia has very cool driver ... "plug and play"
Configuring dedicated Physx was never easier like this before.

Thanks,

Simply not worth it until more games are available. If DAO supports, I may get a $100 card. I'll be playing that game a LONG while given how hard it is. But if the feature is sparingly used, I might not.
