Welcome to The Bug Genie

Once in-game, there's a kind of lag that happens, pretty close to the famous lag one can face when playing on-line. For half a second, the game will suddenly slow down, almost stop, and then for another half a second the character will move really fast. Sometimes it is pretty light, my character will speed up slightly, sometimes the game freezes and then I am Flash for 3 full seconds. :D This mostly happens when passing over or close to things with which you can interact : characters, corpses, animals, etc. A similar bug has already been reported months ago, but it takes place much later in the game. In my case it happens as soon as I leave my cell and fight the guarding goblin. Also, I'm using an AMD Athlon 64 3000+. A single core processor. So this bug can't be related to the Dual and Quad core processors only. I'm using XP too. SP3. 32bits. Weird thing in my case is that Arx Fatalis was once running flawlessly on the same computer (nothing has been changed) and now it bugs. I've tried different things, nothing worked. It happens in Arx Fatalis 1.17, 1.21 and also Arx Libertatis. Even with the non-official patch (0.03? something like that).
