Xemu explicitly prioritizes accuracy over speed. On a modern mid-range CPU (e.g., Intel Core i5-12400), Xemu can run many 3D titles at near-original frame rates (30-60 FPS), but some demanding games require a powerful GPU (NVIDIA RTX 2060 or better) for full-speed Vulkan rendering.
Early builds of xemu were notorious for "green screens" (shader compilation errors) and vertex explosions. Today, the emulator boasts a compatibility list that includes heavy hitters like: Xemu explicitly prioritizes accuracy over speed
While XQEMU aimed for cycle-accurate emulation (which is computationally expensive and slow), xemu shifted focus toward without sacrificing too much accuracy. Intel Core i5-12400)
