Same issue here. Playing SMP with the latest dev build. Launcher/pack Version: Technic launcher 0.5.4.9 set to "always dev build" (2.1.0 | 1.1). Operating System: Win 7 64bit. Version of Java: Java 7 64bit. GPU: AMD 5850 x2 with 12.1 and 12.2. I play in windowed mode though so CF is ofc disabled. Description of Problem: Same issue. When I log on a specific chunk makes my drivers crash. (The chunk contains rotary macerators, induction furnaces, extractors and compressors.) This chunk made one guy on my server lag down to around 10 fps. A third guy had no issues entering my house/this chunk. I also tried logging in from my HTPC and it had no issues at all. I've tried updating to the latest set of drivers but that changed nothing. Error Messages: N/A Link to pastebin of log: http://pastebin.com/R8KpHJZ9 Edit: I gave up on trying to fix this. A couple of hours later I found myself bored so I tried logging on again. After running around on my server for two hours I returned to my house. This time I could load the chunk I thought was causing the errors without any issues. Merrily returning to my turtle-mining business I a few minutes later had minecraft crash. When I logged back on, I got the same error again. However, the only machines nearby this time are a few mining turtles and maybe a redstone engine/tank/pipe setup. It seems I really have no idea what's causing this. New log: http://pastebin.com/3zvNkXLz Note that the crash I'm talking about occurred just before the restart of the launcher at 05.44, the last message prior to that restart of the client is 44 minutes earlier. Around line 500.
