Games work fine. Destiny 2 running between 60-120, avg 84fps.
Theres no way this is running on software or any inbuilt motherboard gfx card.
Software doesnt show Gfx card. Blender, Adobe Suite (CS6), Meshroom. They all report no Cuda Cores. Know for a fact that my card has 2304 Cuda cores
Vulkan use crashes programs. Found if use an emulator (cemu, yuzu, PPSSPP will crash if i select Vulkan, this wasnt the case in the past (its been doing it for a year or more) & could use PPSSPP in Vulkan
Not sure what else I can do. Other drivers I should update?
Ok, let me first get 2 misconceptions out of the way.
If games are running or not is no indicator for a working CUDA environment. CUDA is a computation tech for number crunching on GPU. That’s what Cycles does on your GPU, totally different from gaming.
Also Vulkan is of no interest since Blender doesn’t utilize it.
Info I can find about the 780 indicates that it should have the capabilities to run Cycles ( >= CUDA 3.0) and the driver is up to date. Now while technically CUDA toolkit isn’t necessary for operation of Blender we can use it to at least verify a working environment. What I would do is to look into the CUDA examples and try to compile/ run one of them in order to see it working.
If that’s not the case I’m tempted to blame it on faulty hardware.
Since Windows is not my field it might be worth to open a problem over at dev talk to get the Gurus in on the issue.
Edit: Your screens of GPUZ seem to confirm CUDA not found ( see the checkmarks at the bottom.) But shows driver version 441.41. So there’s something funky going on.
glad it isnt just me who thinks its bizare!
I have downloaded the CUDA toolkit & installed but realise i need VisualStudio installed first. VS19 ask if want any other packs installed, I presume I just need the basics, then reinstall CUDA toolkit and follow this section for the CUDA examples you mention
In some ways I hope it is just a Graphic Card harware issue so ive got an excuse to replace it… but If it still doesnt solve it … ;_:
Haha, that really sounds like development under Windows. While I have no experience myself, I keep hearing of such frustrating hurdles. I hope for the best.
Depending on your budget and the market you’re in you can simply try another card and return it if stuff hits the fan. Or try it with a card of a friend, maybe?
Got it working!
375.50 driver
Had already tried bunch of drivers and none had solved the issue.
Supprised that other older drivers hadnt worked. Sure Ive tried older/newer drivers, but this magically worked.
Installed 375.50 and checked GPUZ and suddernly saw the CUDA tick box was ticked!
Opened Blender Settings and crashed
BUT donwnloaded 2.90 and everything was fine, menu loaded, could select CUDA options. Save with Adobe suite.
And finally Meshroom worked and had some great results!!
