Hi,
I am under W10 x64 pro and I have a GTX 980 Ti 6 GB VRAM. At least 6GB for working mode with some temporal effect OFX (Neat Video for example temporal 5 and with 4K and larger).
On the site : Neat video (
https://www.neatvideo.com/bugs.html#Resolve) it is written:
"
Current versions of DaVinci Resolve are very demanding when it comes to the GPU memory resources, especially when Temporal Noise Reduction (built-in filter in Resolve) or third-party OFX plug-ins doing temporal processing (like Neat Video) are used.
This may become a problem when working with large frame sizes, like 4k and larger. For 4k timelines, Resolve 11 officially requires at
least 4 GB of GPU memory (on each GPU) under Windows and 6 GB of GPU memory (on each GPU) under Mac OSX.
Resolve 12 requires 8 GB. However, Resolve may experience a shortage of GPU memory even when those requirements are met, and especially if they are not met by the hardware. When that happens, Resolve will show an error message:"Yor GPU memory is full. Try reducing the timeline resolution ..."
To avoid such a problem please either run the software on machines with larger GPU memory or decrease the timeline resolution. It may also help Resolve processing to not run its processing on the same GPU that is used to driver the display.

(There is an inflation of VRAM each version of DaVinci Resolve?)
