Made this test 5 times in a row for each double scenario to get the best result from each.
We will begin this test with an "official" (not really) NVIDIA Physx benchmark tool called Fuildmark - if nothing else this tool will surely show if any additional hardware improves FPS when handing particles.įirst of all i've made this test from different testing places - one near the fire, another in the outside like in the picture, so that all the clouds, vegetation and birds would amount for physics particles, and then i summed up the results from both test places. But the most important thing is that every tested game has particle effects on screen - whether that game is officially supported by NVIDIA Physx i do not care. Some games have their own benchmarks, for others i use custom Fraps MIN/MED/MAX benchmark tool, different time-bench for each game. I've tested 17 games at 1920X1080 resolution with all effects maxed out, but with no anti-aliasing as i think this is the most popular resolution and it does not bottleneck GTX980 Ti so much. Asus GTX980 Ti Strix is no longer the top dog of GPU world, even though according to Techpowerup it is faster than R9 Fury X, Titan X Maxwell and R9 295X2. I am sorry for making this benchmark quite late. Physx is set to Asus GeForce GTX980 Ti Strix 6 GB. Physx is set to Palit GeForce GTX650 Ti Boost 1 GB.Ĥ. Physx is set to Zotac GeForce GTX970 AMP Omega Core 4 GB.ģ. Let's see how does this work i my testing rig, which has Core i7 5775C CPU, Gigabyte Z97X-Gaming 3 SYS, 2X8 GB DDR3 1600 MHz CL8 RAM, Samsung Evo 500 GB SSD, GTX980 Ti, GTX970 and GTX650 Ti Boost video cards.ġ. Physx is set to to a single high-end GPU. Physx is set to a fast low-end gaming GPU, while main rendering is set to single high-end GPU.Ĥ. Physx is set to a powerful mid-range gaming GPU, while main rendering is set to single high-end GPU.ģ. Physx is set to CPU, while main rendering is set to single high-end GPU.Ģ. I've created 4 different popular scenarios how NVIDIA Physx is being used by gamers of the world:ġ. You should have an idea what those are by now: any weather effects, explosion debris, fire, cold, dust, smoke, interacting small 3D objects like vegetation, gibs, fragments of material. The purpose of this benchmark is to find out if NVIDIA Physx middleware helps to improve performance in terms of FPS in games, which use any particle physics effects.įor this test i have selected only those games, in which i can clearly see the usage of particle physics being rendered on the screen. Once in a while a random thread or video pops in the internet displaying how NVIDIA Physx algorythm runs a certain game with random video cards, but that is it.
this is why some companies still choose to go with havok and the like, which actually costs money but can do physics calculations on all cores on the CPU in parallel.This time around i've decided to check something, that has got little popularity and variety in the internet: NVIDIA Physx performance evaluation for gaming.
It also has crippled performance, as nvidia limited it to one CPU core only (it was multi core capable when they bought it) in order to maximize the disparity between it and GPU physX.
#Do i need nvidia physx reddit free
Most just use physX as a free CPU physics engine. Unfortunately for nvidia its not as simple as it should have been, and as such very very VERY few companies have done so. in the hopes that companies would implement it and then say "well, we might as well spent a tiny bit more effort to implement the system we already use and are familiar with on the GPU". The most used physics engine in the world by a big margin because nvidia made it completely free. No games exist in the market which take advantage of it and are worth playing. GPU accelerated physics, requires an nvidia card capable of DX10 or above.
