Hi, The problem: weird jerkiness/skipping while moving/looking around, and the screen looking like it has a very low refresh rate in, when it doesn't. This happens the worst when played with crossfire, and still happens, when played with C/F disabled. This problem is the worst when i play farcry 2 (single player) and happens to a lesser degree in other games like left 4 dead 2. Now the weird thing about this problem is that it has only just started to occur recently. All my games, including farcry 2 used to played silky smooth, with zero jerkiness / skipping. I played farcry 2 for 6 months with no problems at all, on 1400x1050, 8x AA, dx9, v-sync off, details all maxed out, cat's 9.11, and i used to get a constant 130FPS when played on crossfire, and it was great, loved every minute. But now the only way i can play farcry 2 is with the settings set to 800x600, details set to low on everything, dx9, v-sync off, with C/F disabled. But even at these really low settings, the game still plays as if it has a 20Hrz refresh, when in actual fact the refresh rate is at 60Hrz, and there is still a little bit of skipping. I am really struggling to work out why the game has suddenly started doing this. Obviously the first thing i thought was that something must have changed with the system, in order to effect farcry 2 in this way. The only thing that has happed recently that might have effected farcry 2, was the fact that i updated Direct X 9.0c (http://www.microsoft.com/downloads/details.aspx?FamilyID=2da43d38-db71-4c1b-bc6a-9b6652cd92a3&displaylang=en) My usual approach to updating is that i try to avoid doing so. If all my games are playing well, i generally will not update my catalyst drivers or direct x. I have found that this approach has always worked for me, if it ain't broke, don't update it So why did i update direct x then you ask ? I updated it in an effort to try and fix stuttering issues in another game (left 4 dead 2) It didn't work, but after the update is when farcry 2 started exhibiting jerkiness. The question is, can a direct x update really brake a game ? So then i rolled back the dx9 update with system restore, but it had no effect, seems as if farcry 2 has been permanently borken... and no combination of in-game setting makes any difference. Farcry 2 is a really fun game. I would really appreciate any input on helping to fix / determine why it's has become unplayable. P.S. - * Farcry 2 Version = 1.03 * The jerkiness in left 4 dead 2 (that i was trying to fix with the dx9 update), is also a recent development, i played L4D2 for about 3-4 months prior with no problems at all. - The jerkiness in L4D2 only started to happed after i installed crysis & crysis warhead about 2 and a half weeks ago. * The reason i never played farcry 2 in DX10 was because farcry 2 has a DX10 memory leak (Officially confirmed) that doesn't effect everyone, but it did effect me, so i switched to using dx9 when i first installed the game. Thank you.
