Last week we talked about a Nvidia drivers, starting with version 186, that disable GPU PhysX acceleration when ATI hardware is also present in the system.
Nvidia gave several reasons of why it decided to cripple its own hardware when in the presence of competing hardware, but in the end, it was just about business.
"For a variety of reasons – some development expense some quality assurance and some business reasons NVIDIA will not support GPU accelerated Physx with NVIDIA GPUs while GPU rendering is happening on non- NVIDIA GPUs," Nvidia's customer service wrote to a user. "I’m sorry for any inconvenience caused but I hope you can understand."
Of course, the setup of having both Nvidia and ATI GPUs in one system are exceptionally rare, making this a very special case – but still a very annoying one, especially for those hardcore enough to employ an Nvidia GPU just for PhysX.
Luckily, someone has created an experimental patch at lifts the handcuffing of Nvidia GPUs when an ATI Radeon is in the vicinity. Those with such specialized systems can thank GenL of the NGOHQ Forums.
This patch, of course, is for Windows 7 users as it's the only platform that'll support configuration for multiple GPUs. Check it out here.
I disagree. I am currently using a 8800GTS, and am planning on getting a 58XX in a month or so, and was going to keep by GTS in my system for PhysX processing. I imagine many people may do the same also.
Back to the Time out bench for nVidia :p
I had no doubt somebody would do this.
Now that is something I would like to see and I think everyone else would too.
Just think of the possibilities if they would combine their efforts.
yeah, I think this is exactly the point. what a massive coincidence that nvidia does this just after the ATI 5870 launches and takes the performance crown from them? there are alot of people using nvidia gpus, specially the awesome 8800gt like me that will be looking for an upgrade, and nvidia is trying to give us a reason for holding off buying this new shiny ATI card dumped in front of us, and wait for their new cards. it would almost be commendable if it wasn't for their Dick Dastardly way of doing it!
All they have actually managed to do is piss everyone off, and not actually succeed from blocking ATI users from nvidia physx. and it would so obviously be hacked too. I mean it may have worked if your market was mainstream n00bs, but its not, its hardcore users like us who will have no trouble using this hack.
