Havnt been on this forum in a good long while, anyway
System - Windows 10 Home 64 Build 10240 Intel 4670K Stock EVGA GTX 970 SSC EVGA GTX 760 for Dedicated PhysX 16GB RAM
All over the internet, everyone says that if you have your secondary Nvidia GPU dedicated to PhysX, The GPU's Video outputs are disabled since the GPU is only being used for PhysX Calculations. Also seems most of this is severely outdated information. This led me to not use the outputs on said card.
I have a HP2311x with 1 HDMI, DVI and VGA and an older HPw2207 a friend gave me recently with only VGA and DVI. My GTX 970 only has one DVI port and Im not going to use HDMI, Yuck
Well, I decided to plug the w2207 into the card that is currently being dedicated to physX and Voila, it works.
So...is there any official documentation on what works and what doesnt? According to everything ive found on the internet, this shouldnt work...but it does, so Im somewhat confused....
Am I missing something?????
Even when launching a Hardware Accelerated PhysX game such as Batman Arkham Asylum, the second monitor continues to run, and the PhysX overlay claims PhysX is being done on the GPU....
Im actually receiving a decent FPS boost in Hardware Accelerated PhysX games.. Around 5-15 FPS Card also has high enough Compute capability to dedicate to PhysX FLEX, where Im seeing the highest improvement.
I even saw a decent FPS boost in Arkham Knight
Besides, what other card would you pair it with if it wasn't a Nvidia card? Last I check, that old driver hack doesn't work on AMD anymore
How PhysX, GameWorks or any other Nvidia proprietary technology harms AMD's performance is not really the point of this post but yes. Honestly, If AMD's architecture was faster at processing tessellation, I doubt it would be as much of a delta as it is
Thats the entire point of having a dedicated PhysX Processor, free up more performance on the main card and allow the lesser card to do all the PhysX calculations.
You asked what I would do, and on the tessellation front, look at TressFX vs Hairworks, TressFX works fine on both cards because it's open, Hairworks wrecks both cards, but it wrecks AMD more, and even if AMD were better at tessellation, the source code is still locked down for gameworks, preventing them from optimizing.
I don't see any reason why it wouldn't work. Maybe if you're running a 3D application on that second screen but even then it should still work. As far as I know physx uses the CUDA stuff or the shader or clock or whatever, so the card is still there and can still do stuff, it's just that it's going to be doing physx as well as displaying whatever it's displaying.
I have SLI on my system and the default is to use the second card for physx (don't know why it can't balance on both cards but whatever) so if it can do SLI and still be dedicated to physx then I don't see why it can't just be used for a second display.
And like you said you tried it and it works, so you learned a valuable lesson about people talking shit on the internet :P
