I do believe it cannot be done. One of the warnings re downloading 9b is that it changes sooooo many things the only way to roll it back is to do a reinstall of the winxp operating system. System restore will not correct the problem either as 9b updates the restore files during its installation. Sorry to be the bearer of such bad tidings before Christmas but that's my understanding. Have you upgraded the drivers for your GPU card? This can sometimes correct any incompatibilities.jasmin said:Need somebody's help I think DX9 slows down my system (WinXP Pro SP1) so I want to downgrade to DX8.1.
Any ideas?
