mastershotgun Posted February 22, 2020 Share Posted February 22, 2020 Hello Devs, Do you use Nvidia Physx to do the physics calculation by any chance? The questions is more about that I have option to get my self another gpu and nvidia drivers support offloading it to the secondary gpu (not talking about SLI), will that help with the framerates, specially in the VR? Or would be the impact negligible, if any? Thank you. Link to comment Share on other sites More sharing options...
Aluminum Donkey Posted February 22, 2020 Share Posted February 22, 2020 Nvidia PhysX is proprietary (owned by Nvidia exclusively.) DCS doesn't use it for that reason--kind of like RTX Raytracing.

RustBelt Posted February 23, 2020 Share Posted February 23, 2020 although it is open source you will not be able to use this nvidia driver feature w/ an AMD card - thus not compatible... Well it will run on your CPU if you have AMD, which since DCS is only using a couple threads, you would have the CPU to spare. But, it would be better running off the card for memory logistics.

PhysX is used in: Call of Duty, Assassin's Creed, Arma series, Metro series, The Witcher 3: Wild Hunt, Warframe, Killing Floor 2, Fallout 4, Batman: Arkham Knight, Borderlands 2, Star Citizen, Ghost in the Shell, Warhammer 40k EC, XCOM series, Warframe, Planetside series, Mafia series... It is supported natively in engines like Unreal, Unity, and BigWorld. Didn't realize those games and engines didn't work on AMD! Link to comment Share on other sites More sharing options...
Fri13 Posted February 25, 2020 Share Posted February 25, 2020 Physx is soooo 2005-ish. Do you guys remember the stand-alone acceleration card they put on sale? It was a disaster business-wise Yes, that card comes to mind every time I read "PhysX" It was such a one week hype back then. It was then nice that it was premised to come to GPU's but as Nvidia bought it and integrated that card features to their GPU, it became Nvidia only. It is a cool tech. Totally are. But it is so niche feature really that it is not worth the CPU or GPU processing time! In DCS I would like to see that for things like ground morphing when exploding, vehicle armors going to pieces and bending, but all that I want to be CPU related! And let's be honest, such a mechanism is already coming with that new damage modeling and new terrain engine. So no need Physx for that! So for what the PhysX would be used? Anyone? i7-8700k, 32GB 2666Mhz DDR4, 2x 2080S SLI 8GB, Oculus Rift S. i7-8700k, 16GB 2666Mhz DDR4, 1080Ti 11GB, 27" 4K, 65" HDR 4K. Link to comment Share on other sites More sharing options...

The engines works on AMD, but you can't go to game settings and enable the PhysX back then. Now you can get it to run on CPU, but it is really not so.... Impressive anymore. https://community.amd.com/thread/241480 https://gpuopen.com/ i7-8700k, 32GB 2666Mhz DDR4, 2x 2080S SLI 8GB, Oculus Rift S. i7-8700k, 16GB 2666Mhz DDR4, 1080Ti 11GB, 27" 4K, 65" HDR 4K.

SkateZilla Posted February 28, 2020 Share Posted February 28, 2020 They work, just w/ PhysX Off. There's no point in using a Physics Middleware SDK when DCS Uses it's own physics engine already.

Now you can get it to run on CPU, but it is really not so.... Impressive anymore. You had to have an nVidia GPU to install the driver, the nVidia Control Panel wouldnt install and function correctly w/ an AMD GPU installed. I used to run a 8800GTS just to run the PhysX and the hassle of installing Control Panels and drivers was just too much.

mastershotgun Posted March 4, 2020 Author Share Posted March 4, 2020 Well guys, the root of my question was to know if it is worth to buy another GPU for offloading the PhysX to it, so I can get more FPS from my main GPU since I'm playing in VR. And got the answer that the DCS do not use it at all, so oki I'm considering my question fully answered. Do not really care about the other games and what they are using it for... The moderator, please lock this thread down. I'm considering my question fully answered. Thank you all for participating, do not want to start any flamewar...
