"Unlocking Resizable BAR Support for Nvidia Turing GPUs: A Risky Free Mod"
Unofficial NVStrapsReBar UEFI driver enables Resizable BAR support on older NVIDIA GeForce RTX 20 & GTX 16 "Turing" GPUs, allowing the CPU to access the entire GPU memory space through the PCIe interconnect for potential performance gains. Flashing a new UEFI image on the motherboard is necessary for Turing GPUs to enable ReBAR, and while the tech offers increased performance, it may not benefit all games.
