    Eran Badit of NGOHQ.com successfully modified NVIDIA CUDA (Compute Unified Device Architecture) to operate on an ATI GPU and has been able to run the NVIDIA PhysX layer on an RV670, the Radeon HD 3850.

    He tells that enabling PhysX support on Radeon cards is not particularly difficult, leading us to believe that physics on graphics cards may not so much be a technology problem but an issue of corporate dynamics.

    On his first run, Eran got a 22,606 CPU score in 3D Mark Vantage, enhancing the overall score to P4262. A comparable system without PhysX-support will cross the finish line at about P3800.

    yup i was waiting for this.. ati wouldn't buy cuda licenses and all from nvidia only to implement a while down the road.. they want cuda drivers from nvidia, this way their cards can compete with nvidia cards in all of nvidia's arenas.

    Something of this sort had to happen, else 3DMark Vantage would have lost its credibility as a neutral benchmark for the industry.

    Technically "open source" means even Homer Simpson can use it. The complication is that whether or not CUDA is open-source, PhysX definitely isn't and is bound by NVIDIA's policies.

    i thought it was like an sdk for developers.. i understand that part of open source.. but is it open source in terms of gpu architecture and the gpu side?

    Yes, it's an SDK open (as in you can use it if you abide by NV's policies) to developers. Not very long ago, NV ran contests for "best CUDA apps", in an attempt to popularise it. The SDK could be downloaded for free.

    seeing how similar the 2900XT is to the 3800's, im pretty sure it will work

    one thing is certain though, if these physx mods are moved to the 4850 and 4870, nvidia will be f*cked

    I'm sure Nvidia put restrictions on the SDKs they released to developers. One way or another I'm sure Nvidia is looking for blood. You don't acquire a company like that only to hand it to the opposition.

    Thanks mate. I've not sourced a large image so far. I'm looking up. I can see a "GDDR3". Edited.
