AMD’s Smart Access Memory benchmarks have alluded to some arguably negligible gains in game performance, but the technology behind it, Resizable BAR, appears to contain some interesting surprises. Japanese hardware site ASCII.jp (via VideoCardz) recently tested an ASUS ROG Maximum XII Extreme/Intel Core i9-10900K/AMD Radeon RX 6800 XT system with the feature enabled and discovered a massive, 182 percent increase in minimum frame rate performance for Red Dead Redemption 2 in 1080p.
