i am still begginer with vray so may be i dont know how to proper set it yet to optimize gpu perf.Īnyway if you could guide more into some gpu rendering stuff (i am reading all the available documentation and some max tutorials).Īlso a vray device select says gtx 1080ti cuda 6.Please note, V-Ray is supported on Blender version 2.79. i still expect more performance from these cards and vray. and render times are 29sec for gpus(including export additional time) and 42 sec in cpu as showed in the screenshot. may be in more complexe scenes gpus will stretch legs so i downloaded a scene provided by bdancer.
but i was still hoping that 4 gpus can do 2 to 4 sec per frame concidering the simplicity of the scene and then it struck me. i tried a really basic cube scene with a sun and the render times are 18s in gpus and 7 secs in cpu but then i got the idea it may be the export time that is making the difference so did animate the cube and rendered the animation and only then the first frame was 18 secs and all other frames did 7 to 9 sec/frame in gpus and cpu kept its concistancy of 7 secs a frame. also after a lot of tries i think i got something. In vray benchmark my gpus are clearly superior to the cpu thank god.
upping the rays per pixel as bdancer told me didnt change anything in my render times. i attached a screenshot of what you asked. the build is several builds from this week. check the selected devices for GPU rendering.Ĭheers,Hi boyan and bdancer, Thanks for trying to help i really do appreciate it. If it possible to share with me and ocldeviceselect.exe window. V-Ray benchmark can be downloaded from here. Can you share the scene file and V-Ray settings with me? What is the build number of V-Ray for Blender? Meanwhile, for the reference point for you can use a benchmark test.
