Changing The PhysX Settings: Does It Really Matter?

[RMTM]

Changing the PhysX settings from "Auto-select" to your discrete GPU. Does it really matter? What effect can it improve? And Why is it "Recommended" to "Auto-select"? Aren't discrete GPUs' PhysX supposedly better than the CPUs'? 

 

Need to set my display to its full potential to make my money's worth of experience. Need your expert/experienced insights on this one.

 

Thank you in advance.

I am not an expert but unless you want like the last cents out of your investments auto seems adequate also lots games don't use PhysX according to NVClean Install which you should use for your Nvidia drivers because they are much cleaner and removes telemetry.

I always set it to GPU. I've noticed a difference in games such as battlefield, tarkov

I'd keep it at auto. PhysX is dead either way. There are many ways to emulate physics nowadays, some use GPU, other use CPU. The last game i remember where Nvidia's PhysX was implemented was Borderlands 2.

Thank you. Agree on clean install. But will clean install always reset and remove your current customized settings?

Thanks. I'll keep this in mind, to try.

Agree. I think it's logical and make sense to put it on "Auto". Since I always just let the application decide on how 3D will be utilized/applied.

What do you mean by customized settings

Settings on Nvidia Control Panel and GeForce Experience. All returns to default after clean install. I have to redo my settings every after clean install. I don't mind though. It can only happen once every update arrives.

I found a alternative called NVslimmer https://forums.guru3d.com/threads/nvslimmer-nvidia-driver-slimming-utility.423072/ as far as I know it deletes the parts you don't want so you should be able to keep your configs and as far as I know NVIDIAClean Install retains only the Nvidia Control panel settings

Interesting. Thanks!

I have to agree to disagree. This setting, as weird as it sounds can fix different stuff. For example did it fix an issue where a laptop didn't render correctly in a CAD program, which resulted in poor performance. They should change it to say. Perform physics on GPU or CPU. Sometimes the auto setting, dosen't choose the right processer for the job, due to poorly designed games or programs I guess.

I think it is in one of those isolated cases in other hardware combos. I am also using a Computer Aided Design software in my Predator Triton laptop. But I haven't had any issues in rendering so far or with the use of CAD for that matter. I just replaced the optical HDD that came with it to an SSD to make saving and extraction much faster. My Triton have UHD630 and GTX1650 set on Auto-select PhysX.

I would test it in the games you use. gg

Cool. I play my games on my desktop PC though. Not with my Predator. I'm curious how'd be your experience with the same games I use/play. Let me know. Thanks!

Same, what games?

Halo Infinite, Halo Wars, Shadow of the Tomb Raider, Cyberpunk 2077, Forza Horizon 4 and some Valorant on the side. And I still have the Marvel's Avengers (still gives both CPU and GPU some workout).

Dont play any of those games, sorry

Oh, why? What were your experiences playing with all of those? What part you didn't like in all of those? Pointers from you maybe?
