The custom resolution fix in nVidia control panel doesn't work for me, because every time I use that custom resolution, for whatever reason, the game becomes extremely dark. I can force it out of 24hz by disabling and then re-enabling vsync. But, God forbid if I alt+tab out to do something else real quick, it reverts back to 24hz and I have to go through the disable, re-enable vsync workaround again.
You are ignoring a glaring problem that a large portion of your community is experiencing. If this is the kind of support I can expect post-launch, then you have lost a customer and a fan of your franchise. Crysis 2 will be the last Crytek game I buy unless you actually put the effort forth to fixing your bugs. I have a huge library of games and the Crysis series are the only ones that this happens with.
