Nvidia Disables PhysX Support on Vendor Mixed GPU Setups - Driver Update 340.52 Onwards

The folks over at BSN made a pretty interesting discovery in the contempo Nvidia driver update (340.52). Evidently, this commuter update makes a very hidden but significant change to the drivers. Basically, if the drivers detect a second non-Nvidia GPU in the system, Physx support would exist disabled and the program in question would fall back to CPU Physx. Yet, even though the change is significant, its impact would be almost negligible for the simple reason that mixed vendor setups are very rare. NVIDIA-Shield-Tablet-1-750x400

Installation of a 2d Non-Nvidia GPU would Disable PhysX Support from 340.52

I can see that the heading itself is quite disruptive, so I will begin with what exactly Nvidia ways past a mixed vendor setup. Basically the only vendor that doesn't interfere with the working of PhysX later on this update is Intel HD graphics (and Nvidia itself ofcourse). But await, that only leaves AMD doesn't it? and why would someone mix red and green GPUs you lot inquire? Well thing is, if you have an APU, I am pretty sure that would count equally a Not-Nvidia graphic carte; unless the hand over to the dedicated Graphic Card is perfectly clean. Some other alternative scenario, something that BSN mentions, is those dedicated PhysX cards of erstwhile. Not sure if anyone is all the same rocking them just the numbers, if any, should be quite few.

Another important update is that PhysX will now work merely on Geforce 8 Series and above. And if you lot misread the nomenclature that is eight and not 800 so nosotros are talking most the lineup which housed legends like the 8800GTS. Another requirement is a minimum of 256MB vRAM which once over again shouldn't affect any significant number of gamers, because if you are rocking 128MB vRAM or beneath, and so you certainly can't beget Physx effects. Ofcourse, all this happened out of patently sight. The chief allure of the 340.52 driver update was the inclusion of Nvidia SHIELD Tablet support. This will still serve as a warning to the odd young man who is thinking of getting a vendor agnostic setup, the nigh probable scenario beingness one with an AMD APU and an Nvidia GPU. There is, however a catch. Nvidia didn't brand very clear, its criteria for turning Physx off apart from the usual statement of improving feel. That means we don't know with complete certainty which of the to a higher place situations will really outcome in PhysX beingness disabled.
