Of course the latest and greatest (stupidly installed Geforce Experience which has kept me up to date), I tried rolling back to an earlier version which didn't work out to well as it gave me a black screen and an endless reboot loop. I'm going to have to bench it for a week or two now anyway as we're stacked with work, but I have just snapped up a secondary Titan X to test to see if there is any joy with another card - failing that onto Chaos Group. I'll keep the thread updated with any progress. Cheers

A quick update - new test scene again: Reset Max. One standard 1000mm box. One ground plane. Standard material throughout. Single HDRI (Guthrie) in Dome 4000 x 2250px RT al the same as above... 3 hours + render times - I got bored of the same 4 walls so I stopped it at that point Has anyone had the same kind of issues or does anybody have any inclination as to why this is rendering so slowly? Driver issues etc? Surely for 7 polys, a standard material & a hdri this cannot be correct?

Cheers Joel.

PS. I have the engine type set to CUDA. OpenCL simply doesn't render at all...

Yeah. I can also see in GPU-Z that the card is getting 99% GPU load when rendering - memory used never gets above 4666mb - GPU Core Clock 1303 - GPU Mem Clock 1652 - mem controler load averages at about 10%

Hi Scott.. Cheers for the response, I'm honestly loosing my mind here as these render times are insulting to say the least! I'm rendering out to 4000 x 2250px - not the smallest I know but I've also tried 1920x1080 and that's still ridiculous. I've tested a new scene that consists of 4 walls, ceiling, floor, 3 windows & a dome light (Guthrie HDRI - no other maps) - & I'm still getting the same kind of render times.. I'm utilising ggx shaders for glass plastic & paint but I've also tested without. I'm using a max physical cam with pretty standard settings - no dof or mb. I've tested cycling up and down with the bundle size & rays per pixel to double check that I'm not overdoing it in terms of memory... In terms of optimisation; I guess that you are referring to modelling wise (proxies etc) as all material / light subdivs etc are unavailable , if so then I'm pretty sure our models are more than adequate - this also reflects in the vray messages showing 10gb+ gpu ram still available at render time. I'm pretty sure that something is amiss as my last test scene couldn't get much simpler. Any thoughts on how to proceed?

I've just started testing out RT GPU rendering for the first time and I seem to be getting excessive render times (8 hours) to produce near noiseless images (max. noise 0.02) for relatively simple interior scenes. Obviously with optimisation vray adv can outperform these render times ten fold. I believe I have set everything up right in RT: CUDA, in process, coherent tracing, max render time 0, ray bundle size (512), Rays per pixel (128), Trace Depth 5, resize textures, disabled probablistic. I'm also using light cache (+glossy rays). I can see that material / light subdivs etc aren't applicable so I'm wondering what could be the cause of these excessive render times - or is this expected?? Workstation config: Titan X 5960X 64gb ballistix sport 3dsmax 2016 vray 3.3 FYI. We had anticipated using rt as part of our sign off process & purchasing another titan x but we're unsure if it is a wise choice now... Any comments / advice etc will be appreciated!

Cheers for the advice - I'll go for the EVGA SuperNOVA 1300G2 so I've got some headroom for the third card. And I will definately look at overclocking in the intrim Dimitris - great info!

Hi all. I'm planning on my first workstation build and wanted opinions and advice before I take the plunge. This workstation will be used primarilarily for 3dsmax 2015 & vray 3 rendering, photoshop / fusion for editing (no gaming). I'm looking to utilise GPU rendering for retail renders not needing advanced mats or disp & also fusion editing - max scenes are often large thus the 12gb Titan X in my below spec, whilst still retaining a good spec'd cpu workstation as we don't have any render nodes atm. The build specs I have so far are as follows: i7-5960X Noctua NH-D15 X99-DELUXE Crucial Ballistix Sport 32GB (4 x 8GB) - (future upgrade to 64gb) Samsung 850 Pro 512GB GeForce GTX Titan X 12GB Video Card (future upgrade to 3 way sli) Fractal Design Define R5 EVGA SuperNOVA 1000G2 1000W (to support the 3 titan x cards) The main basis for this build is from Dimitris "Workstation Powerhouse" on pcfoo. Any help and advice would be more than appreciated, aside from some great forum topics I feel like I might be going into this blind so feel free to speak out if I've got it completely wrong - also one last note... This is a business investment so I'm looking to spend the money wisely and not just waste it where not necessary. Cheers!
