Stable speed seem to be 94 Mhash/s for me then I started to fiddle around with the flags and different pools and now I hit a limit at 55 Mhash/s no matter what. I know my speed sucks but I only do this because it's fun for the moment, I do have some interest to get a real mining machine but not at the moment.

Any reason this could be? I've checked and my hardware isn't faulty and it's the only known application I seem to have something wrong with.
