All of this has to fit into VRAM for it to benefit from GPU acceleration if it overflows at all, everything goes to system RAM, and the CPU.
In the NVidia lineup, anything in the 30xx series will do the job for you, performance-wise, but you’re right to be looking at the VRAM–that’s going to be the limiting factor for you when it comes to scene complexity and level of detail.Ĭonsider that HD models from G8.1-9 and 4k/8k/16k textures are going to take up more VRAM than previous generations, and that’s only going to grow over time as people start producing higher-resolution props and settings to go with these figures. Frustrating as hell, but that’s the reality at the moment, and unfortunately the “NVidia or nothing” mentality seems to have become entrenched in the 3D software industry (it’s not just DAZ). You can have the best-performing AMD/Intel/M1 GPU in the world, but if DAZ Studio doesn’t see an NVidia GPU it sends all the rendering work to your CPU. Only NVidia GPUs can render Iray natively (Iray is an NVidia technology), so from a performance standpoint with 3D apps like DAZ you’ll want something NVidia-based.
