Unreal was noted for its graphical innovations, but Sweeney acknowledged in a 1999 interview with Eurogamer that many aspects of the game were unpolished, citing complaints from gamers about its high system requirements and online gameplay issues. Epic addressed these points during the development of Unreal Tournament by incorporating several enhancements in the engine intended to optimize performance on low-end machines and improve the networking code, while also refining the artificial intelligence for bots to display coordination in team-based gamemodes such as Capture the Flag. Originally planned as an expansion pack for Unreal, the game also came with increased image quality with the support for the S3TC compression algorithm, allowing for 24-bit high-resolution textures without compromising performance.[

Like the 868, the 64V+ has a video acceleration engine that can perform YUV to RGB color space conversion and horizontal linear filtered scaling.
