fair enough

[Curtis Ling]

770/780/780ti you might find new and used ones in your budget on amazon (us?)

AND AS FOR THE 970/980 disregarding support they are not even in the price range (well with all the markups anyway)

[Curtis Ling]

like i said i haven’t found any shortfalls yet except cpu fallback and should be a last resort (laptop/non changable gpu etc)
(a laptop with a Kepler GTX 860m or 870/880 is much more expensive than a laptop with a gtx 850m or maxwell 860)
of course there shouldn’t be any problems as the gpu raytracing is called out and i don’t think adobe changed that part.

that said i am not a hacker or coder so i don’t know what the stuff that makes up the dll
and yes i am unsure of support in other programs hence i now recommend the 780/ti

the 900 series should only be considered when the extra horsepower (per dollar) significantly offsets the support uncertainty (that is a 8gb 980 or 980ti+ and whatnot or two 970’s)

ps: as for the 780 official status i know only added to the list makes it work
but in the eyes of adobe neither the 970 or the 780 is supported HOWEVER only the 780 has a supported ARCHITECTURE ATM

[Curtis Ling]

the 780 isnt officially supported in cs6 anyway
the hack only replaces an application extension
it work but only on the gpu
it should be safe as ae only has one dependency so far nothing broke here
i even ran the https://www.loopoutcontinue.com/cuda/ benchmark

one thing tho AE ray tracing is one thing iray/mental ray/whatnot support for SM 3.5+ might take some time
also i am not sure its as simple as changing one file in that case

if you can get a 780 ti for the same price then go for it
the 780 ti is much better than the 970 and the extra bandwidth should make up for the vram deficiency
but for me i want even more vram (8GB or so) which is something the 700 series doesn’t offer
(900 series will soon offer that so for me thats the go)

I don’t mind tinkering with bits so my path suits me

[Curtis Ling]

its only iffy in the sense that cpu fallback doesn’t work
not technically a hack but a unofficial update well semi unofficial in terms of adobe but in terms of nvidia not so much so
(adobe adds to nvidia base dll so …)
like i said to be clear its not a maxwell thing
because unless they update it cs6 raytracing won’t work in a tesla K80 either

[Curtis Ling]

h264 is best for mercury playback engine
uncompressed/lossless pngs and such rarely play realtime
and yes maxwell works for raytracing if you are willing to make one iffy hack
dont throw away the 970 just yet

and for the record it not a cuda issue its the Compute Capability (SM) of the gpu and since maxwell is 5.0/5.2 it wont work
NOR WILL A K80 with SM 3.7
only gpus with SM of 3.5 or before will work (until they update)
this is the optix shipped

this is the email for optix 3.7 beta

“XXXX XXXX
OptiX Manager | NVIDIA Corporation

Enhancements in OptiX 3.7 beta 1

…

· Tesla K80 support with SM 3.7. This is the highest performing GPU for ray tracing.”

[Curtis Ling]

just thought it might be against the tos of both adobe and nvidia or something
besides i don’t think nvidia would want the implementation of a dev only dll maybe only when its public can it be updated

i just tested using 3.6.3 optix.1.dll and replaced the one that came with cs6 and
GUESS what i got raytracing working on MAXWELL GPUs in CS6
still dont know why the adobe one was bigger. EDIT: It seems the new optix.1.dll doesn’t work with CPU ray tracing (maybe adobe implemented additional code so thats why it was bigger)
[simple fix you see]
now we wait for adobe to test things and nvidia to work on licensing or something and maybe next major release will support MAXWELL
same cant be said for design garage tho which also uses a optix version that doesn’t support maxwell. difference is it has other dependencies which needs to be updated (scenix? and cuda?) and that would be too much work.

[Curtis Ling]

how do you know ps i am testing soon

[Curtis Ling]

i wonder if its possible to “update” the optix dll for CS6 with one that supports maxwell (3.6.x)
and its not a “v2” cuda problem
https://blogs.adobe.com/aftereffects/2012/05/gpu-cuda-opengl-features-in-after-effects-cs6.html
The GPU acceleration of the ray-traced 3D renderer depends on the OptiX library from Nvidia, which requires CUDA on an Nvidia GPU. CUDA acceleration works fine on maxwell but the included optix is 3.0
https://devtalk.nvidia.com/default/topic/775928/maxwell-860m-with-optix-3-5-1-and-cuda-5-5-2-working-/
“OptiX 3.6 is required for Maxwell architecture…”
in other words all thats needed is to update optix in support files location. catch is 3.0+ is for devs only

[Curtis Ling]

side by side wroks for me idk how this is
