How do I tell if hybrid PhysX is working?

[ruhtraeel]

Hello, another quick post I'd like to make, about a different matter.

I can see that PhysX is checked off on both my 7970 and my Quadro in GPU-Z, but the usage (I haven't played it extensively in particle-heavy areas yet) always seems to be at 0-1%. Is this normal?

I followed the steps here:

Mafia 2 has a demo, includes a benchmark where there is much physX effects. It should be obvious between off and high, the effects, stones crumbling off walls from bullet impacts, and the physX gpu should show at least 25% or more usage (just guessing).

Also , fluidmark is a physX benchmark.

Run that and watch gpu-z on that gpu.

Wait... do I need to delete PhysXDevice.dll for every game you want to run Hybrid PhysX on?

Do as notty2 said. I don't think there is anything you have to delete, at least not when I did it a couple years ago.

Remember, it only helps when you are playing a GPU accelerated PhysX game, which there are only a handful. It should be obvious based on the performance difference between attempting it before and after.

In batman, if newspaper is tweaking out on an enemy's feet you know physx is working

I can tell in Borderlands 2 that PhysX is working (it's greyed out at high because I changed the .ini file), but the problem is that I don't know if it's using the CPU to do it or my GPU. If it's the CPU, I'm going to get slowdowns in particle-heavy scenes.

Check the other GPU load

Hey my friend, GPU Z should do it.

Ah, it turns out I DO need to delete the PhysX .DLL files. Problem solved!

I'm running a pair of R9 290s and I bought an NVidia card for PhysX, but I'm running into the same thing, I'm trying to figure out if PhysX is running on my NVidia card, or my CPU.
Also, which DLL files specifically? I'm just trying to test it on Metro 2033 Redux. Running the benchmark I was getting the CPU running up to 45%, and that's on a Core i7 5930K @ 4.6GHz. To me that sounds like it's running PhysX off of the CPU, getting ~30FPS in 5960x1080. It does let me select Advanced PhysX.
Fluidmark does not let me choose GPU

Another thing I was thinking of, but haven't tried and wondering if anyone else has. Hooking up a small monitor to the NVidia GPU so you can open the NVidia Control Panel and enable PhysX that way, then run off of the main AMD cards. Sounds too simple to actually work, but thought I'd ask if anyone has tried it.
