Resizable BAR technology, a key capability in today’s processors and graphics cards, is gaining popularity for its ability to optimize system resources and improve performance. Initially supported on specific GPUs and motherboards, the technology has now been extended to many older platforms.
If a graphics card supports Resizable BAR, it can significantly enhance game performance, particularly when paired with AMD processors and graphics cards. However, popular mainstream graphics cards like NVIDIA’s GeForce RTX 20 and GTX 16 still lack support for this technology. While many older products theoretically support Resizable BAR, manufacturers have been slow to implement it. As a result, enthusiasts have turned to unofficial UEFI drivers like “NVStrapsReBar” to enable Resizable BAR on these older cards.
The process of enabling Resizable BAR with NVStrapsReBar requires certain skills and is not as simple as installing a regular driver. While the actual performance improvement has not been extensively tested and may vary, users are advised to proceed with caution.
As for the GTX 10 series, the likelihood of Resizable BAR support being added is slim. Additionally, NVIDIA has officially discontinued the GTX 16 series, which is expected to be phased out within the next 1-3 months. This change signals the end of the GTX name for NVIDIA’s graphics cards.
