I am afraid that this patch does not work for Vietcong.
Does the game have a demo with the same issue?
In short: no.
Long version: the game has demo, but because of bug 9337 it crashed after the intro of first mission. For full game I use community tool "VCStarter", which is somehow workaround for bug 9337 - unfortunatelly this tool is only for version 1.60, but demo is version 1.0. Vietcong use D3D8, but what I understand VCStarter converts D3D8 calls into D3D9 calls (among other things). In intro in demo version i did not see any glitches.
Do you need to see some debug logs?
