flawlesssai Posted March 18, 2014 Share Posted March 18, 2014 I've been able to activate PhysX on most games Via the document files, yet i haven't been able to do it with warframe. Does anyone have some ideas on how to do it? Or did they block it for only Nvidia cards? Link to comment Share on other sites More sharing options...
DecapitatingJim Posted March 18, 2014 Share Posted March 18, 2014 Nvidea only. Link to comment Share on other sites More sharing options...
Kamal965 Posted March 18, 2014 Share Posted March 18, 2014 Pretty sure there are community made drivers for AMD that enables PhysX. Use with caution, though. Link to comment Share on other sites More sharing options...
-dicht.ThanksFrost- Posted March 18, 2014 Share Posted March 18, 2014 Ur not missing much, my 765m can do PhysX and i have it off. It's annoying and nothing special imo Link to comment Share on other sites More sharing options...
Letter13 Posted March 18, 2014 Share Posted March 18, 2014 AMD cards cannot run Apex PhysX effects because they don't have CUDA cores (there are special hardware based instructions within CUDA cores that Apex PhysX effects utilize to process data, operational codes and values which execute at the hardware logic level). Basically, Apex PhysX effects require specialized hardware to run, hardware that only Nvidia has the patents for. Other games that have PhysX special effects are almost always executed on the CPU (a lot of these effects can be run easily on the current generation of CPUs), unless an Nvidia card is present in which case a lot of the workload is offloaded to the GPU; these effects are software based effects. The main effect that Warframe uses, however, is Turbulence Fields, an effect which requires a massive quantity of floating point operations--specifically floating point multiplies, divides, roots and exponent functions. Although these can be processed by a CPU, they can't be processed well enough or fast enough to compete with CUDA cores. In essence, the CPU is a "Jack of all trades, master of none" while the GPU, by default, is designed to handle and process complex arithmetic functions at a high speed for processing vector graphics... as it turns out the same arithmetic functions used in the processing of graphics can also apply to physics simulations (ergo Apex PhysX effects). It's also for this same reason that many high-performance-computers (HPCs) and Supercomputers are essentially a huge array of GPUs managed by a processor.

taiiat Posted March 18, 2014 Share Posted March 18, 2014 -snip- sometimes i think you have 15 different flavor of answers to these common questions on sticky notes and paste a random flavor in whenever someone asks these questions for the Xth time :D Link to comment Share on other sites More sharing options...
flawlesssai Posted March 18, 2014 Author Share Posted March 18, 2014 Thank you for all the Replys! And yes I see, I was hoping to enhance my visuals on the game other than the setting on High. Link to comment Share on other sites More sharing options...

I usually write these sorts of responses on the spot. Link to comment Share on other sites More sharing options...

flawlesssai Posted March 19, 2014 Author Share Posted March 19, 2014 So pretty much, if I want PhysX i need a Nvidia card.. Link to comment Share on other sites More sharing options...
flawlesssai Posted March 19, 2014 Author Share Posted March 19, 2014 I've heard of something called Mantle for AMD which from my understanding, it makes your GPU work more rather than your CPU which opens up for more power but i dont think that would have anything to do with PhysX. I'm currantly using a R7850 and can't aford an upgrade atm. Link to comment Share on other sites More sharing options...
