NVIDIA Control Panel

[TreyInc]

I upgraded my GPU to a GTX 970 recently and I've been wondering what the best NVIDIA control panel settings for the card would be. I'm not sure if I should leave the PhysX on "Auto", "CPU", or "GPU" and I don't even know where to start with the 3D settings. If anyone can post a picture of their set up in terms of 3D settins and what I should do for the PhysX mode, I would really appreciate it.

CPU: The processor will handle the physics calculation (uses a lot of cpu usage)
GPU: The gpu will handle the physics calculation (frame rate might drop a little bit)
Auto: Let nvidia decide whether the gpu or cpu handles it

I choose Auto.

I suggest you leave it on auto. Nvidia already knows which games take advantage if it's GPU accelerated PhysX technology (like hawken) and which ones do but only use the CPU for PhysX (like War Thunder 1.53).

Most of the time you just leave it to default setting. Unless if there is specific stuff that cannot be done with in game options or you want to override certain setting.

So I would much rather prefer it on my GPU but I'm wondering if I'm making an incorrect decision. I don't want to harm my hardware so I'll most likely leave it on my GPU and let my CPU rest unless told otherwise. Anyways, what about my 3D Settings?

On auto that usually set to GPU. But this only dealing with gpu accelerated stuff. Other than that PhysX will ba handled by cpu as usual. People often have this misconception that all PhysX calculation will be done on GPU once nvidia gpu being use.

As for 3D setting you can leave it as it is.

Can I really leave my 3D settings as is? I feel there is so much to offer and so many things to change or optimize, like the Texture Filtering Negative LOD Bias. I see most people with that on "Clamp" instead of "Allow", so surely there's a reason for that change.

You don't really need to change those unless you are facing any problems with any of your games. As for Physx part, I leave it on CPU. When you are playing games, most of your CPU resources are idle and all load is on your GPU. Some games benefit from this since the physx part is being done by CPU and you get more FPS.

With PhysX set to Auto, the GPU will handle GPU-accelerated PhysX, always. Don't try to second guess the engineers who design these things.

According to what you've stated, setting it to GPU is the exact same as setting it to auto as the GPU will "always" handle accelerated PhysX, correct?

Well yeah those control panel give you much more advance option. But you need to know what those setting do before you change them. Granted you can set them per game basis so depending on games there probably some specific setting you want to change. You might want to look around for info first before messing around with those setting.

As for PhysX just leave that on auto. Because if you set them to CPU that will force gpu accelerated calculation being don on CPU. Forcing gpu accelerated stuff to cpu (even if the said cpu is very capable one) is something you don't want to do.

Correct. Either setting will be identical. Don't ever set PhysX to CPU.

Thanks, I appreciate the straight forward answer.
