Several issues with the 413 patch have been pointed out. We will have an updated patch as soon as possible to address these issues. In the meantime, if you are having D3D video performance problems, see Erik's update below. If you are having problems installing UT, or getting an error after installation that "UnrealTournament.exe is not a valid Win32 application" or "UnrealTournament.exe is too big to fit into system memory", try installing into the default directory for UT (c:UnrealTournament). Our patch installer seems to be occasionally corrupting files when installing into different directory structures. We are still working on the problems of the 413 patch not working with minimum installs, and problems patching the Spanish/Italian version of UT.Begint een beetje op de Quake series te lijken, patch na patch na patch na patch.
