Hi team,
I am using Sketchup Pro 2020 with vray 4.20. My computer is a Lenovo P53, intel i7, 32GB RAM and a nvidia Quadro T2000 with 4GB RAM.
When I render 4K resolution images I got this kind of errors:
Using 11 threads for CPU, 6 threads per GPU device
Using 11 threads for CPU, 6 threads per GPU device
Num samples per thread reduced to 32768, rendering might be slower

D:\cgrepo\vraysdk\samples\vray_plugins\rt_private\rt_opencl_pri(3623) : CUDA error 2 : unable to allocate enough memory to perform the requested operation (out-of-mem)
This error appears when I render using CUDA. The result has lot of noise. When I use CPU I got no errors and the image is really clear. Is it possible to use system RAM memory when using CUDA render engine? Another weird think is that I have no D drive, I only have C drive in my laptop.
If I downgrade image resolution, I got no errors using CUDA and the image is clear.
Is there any setting that must be changed?
Thanks
