I use computers with both a Geforce GTX 1050 and a Geforce RTX 2060 Nvidia graphics cards. Although slow, rendering with the 1050 GTX works fine for small scenes without too much data.
Sometimes, I get the occasional "CUDA error: out of memory in cuArrayCreate(&handle, &desc), line 783" (or something similar to this), but I was told that this is due to my scene being too much/complex for my GTX 1050 card to handle and that I need to upgrade it.
When I try using the RTX 2060, I get this error: "CUDA binary kernel for this graphics card compute capability (7.5) not found". From the research I've done, apparently Blender does not officially support RTX graphic cards. I found a few solutions such as adding 'kernel_sm_75.cubin' and 'filter_sm_75.cubin' into the Blender>2.79>scripts>adding>cycles>lib directory to get it to work with my RTX. However, this method and the others I have tried do not work.
Will there be an official Blender release that supports RTX cards soon or should I stick to getting a better GTX card? I'm not as tech savvy as I want to be when it comes to Blender so please let me know if I missed anything. Also, I apologise for the lengthy post.
