Metal Particles (as demo /bench) new Nbody-Metal (demo/bench)

06 November 2015 - 11:56 AM


After investigation it is clear that the DEMO is really more an DEMO, and not usable as bench - because CPU bound limit, very huge cpu loads generating and moving that particles.



From here : https://github.com/F...alKit-Particles


compiled app 2Mill final version:


Screenshoot shows low cpu usage but very high (full) GPU load = i think diff gpus should perform different, compared to the demo below.

12 FPS GT  740

20 FPS GTX 650

some new METAL playground N-body Metal demo   :) , well known as cuda, opencl bench - now computes with metal - but i see that more as an demo,not as an benchmark

threadwidth + maxthreadspergroup may very between drivers/gpu models and are shown as info


Key s switches between METAL devices - if you have more than one.

Info: Metal is limited to 60 FPS - if you run in that limit you can use key + to get more bodies (up to 96K)  = more gpu work, less FPS
