Can I use a rtx graphics card and gtx graphics card, similar to rtx2070 and gtx1660? Can the rtx function be turned on in this case, and what effect does it have on the function?

Hi zhongsheng,
In multi-GPU setups, the amount of RAM available to OctaneRender is not equal to the sum of the VRAM on the GPUs, but it is restricted to the GPU with the smallest amount of VRAM. We recommend disabling GPUs that don’t have enough VRAM in order to render large scenes that can fit in the remaining GPU's VRAM.
