NVIDIA has been pretty quiet when it comes to multi-GPU rigs with their latest Turing-based GeForce RTX and GeForce RTX SUPER graphics cards, but is all of that about to change? Quite possibly.
The creator of SLI Compatibility Bits, a super-useful tool for SLI and NVLink users, recently spotted that NVIDIA silently added Multi-GPU Checkerboard Rendering in their latest GeForce drivers. You'll need to manually enable this feature inside of the NVIDIA Inspector Profile tool by changing some of the settings including SLI compatibility bits (for DX10, DX11, and DX12) as well as the SLI rendering mode options.
Checkerboard rendering isn't something new as it's a method of rendering that's used in some console games, including the PlayStation 4 Pro and its upgraded 4K graphics in some games. But when we're talking multi-GPU configurations the kinda doors that Checkerboard Rendering can open are extensive -- like multi-GPUs working in DX10, DX11, and DX12 titles even if the game itself doesn't directly support it.
It isn't a blanket now-multi-GPU-works-on-everything fix, but it is something that I will immediately investigate this week with my stack of GeForce RTX and GeForce RTX SUPER graphics cards. I've already tested NVIDIA's new GeForce RTX 2070 SUPER graphics cards in NVLink and the higher-end GeForce RTX 2080 SUPER graphics cards in NVLink -- but now some more fun testing will begin.
