Finger crossed : http://www.assettocorsa.net/forum/index.php?threads/game-progress.18152/page-10#post-329341 We found a bug related ALSO to Fmod that might be related to what Matthew and someone else is reporting too, we already solved it in our beta branch and the issue didn't come anymore. FPS drops, audio crackling, multiplayer stuttering is NOT related to a single bug in the dev path, but many aspects are involved. As reported many times, we always thank you for your support and your help, but "I have the same issue" or "it's unplayable!" messages without attached logs means really nothing. I want to underline this point because we know that 99% of the users here are not devs and of course they don't know how the development or bug reporting works. We really respect them and we often understand their "complains", but we ask the same respect because we're working non-stop (14-18h day is quite the standard for us) to solve issues, improve the product and give you a more enjoyable experience (and a faster/better support of course). Read things like "throw fmod away!" or similar is just.... pointless and sad, moreover it denotes zero know-how about development and, most important, lack of respect for the whole team. That said, we're testing with betatesters together with other bug fixes and improvements about phyiscs, ffb and so on. When the devs consider the update is ready, then will be released.
