Dead Space Performance Jumps 46% with Resizable BAR Enabled

The PCI Resizable BAR feature can have a major impact on the performance of “Dead Space” (the 2023 reboot). sxKYLE on Reddit discovered that his GeForce RTX 4080 “Ada” experienced a major performance jump from 76 FPS up to 111 FPS (+46%) with resizable BAR enabled. NVIDIA Profile Inspector was used to enable resizable BAR for the game. The feature allows the CPU to see the graphics card’s video memory as a single, continuously-addressable block, rather than through 256 MB apertures. We can imagine how “Dead Space” in particular could benefit from the feature, as the game’s campaign is a single continuous action sequence with assets being constantly streamed to the GPU (and no level load screens).
