With Windows 11’s optimizations to borderless windowed mode (improved DWM latency), some developers are moving away from exclusive fullscreen. However, for grassroots FSR 2 implementations on Vulkan, the exclusive flag remains a powerful tool for competitive gamers.
| Issue | Explanation |
|-------|-------------|
| No motion vectors | FFX may not provide proper motion vectors, causing ghosting. |
| UI artifacts | Fixed HUD elements may blur or double during upscaling. |
| Exclusive mode crash | Some Vulkan drivers bug out when forcing exclusive mode on older games. |
| DLL conflicts | Overwrites vulkan-1.dll or dxgi.dll, breaking other tools (e.g., ReShade, SpecialK). |
Moving to FSR2, we hit the heart of the matter. FSR 2 is the second generation of AMD’s upscaling technology. Unlike the first iteration (FSR 1), which was a spatial upscaler (using only the current frame), FSR 2 is a temporal upscaler. ffx fsr2 api vk x64dll exclusive

Before FSR 2, temporal upscalers struggled with fast motion and particle effects. They also required specific hardware (e.g., tensor cores for DLSS). Developers using Vulkan had fewer upscaling options. The introduction of the FSR 2 Vulkan API changed that.
When a game uses ffx_fsr2_api_vk_x64.dll, it gains: Red Dead Redemption 2 with mods).
When developers implement ffx fsr2 api vk, they are compiling the FSR2 library against the Vulkan loader. This is often seen in native Linux ports or high-end Windows games that prioritize Vulkan (e.g., Doom Eternal, Red Dead Redemption 2 with mods).
