https://www.techpowerup.com/304346/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).
Some very good info that will help increase performance if your current resizable bar is not enabled.
