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.

    $\begingroup$ Compute capability 7.5 in Cycles requires a nightly build of Blender, see builder.blender.org/download $\endgroup$ – JtheNinja Mar 6 '19 at 3:25

Maybe you know this now, but Blender 2.82 has the Optix option for rendering with RTX graphics cards.

On this day (18 apr 2020), Optix still on the experimental version. In close future we expect that they release the stable version of Optix. If you have a RTX card, you might want to try it out.
