Loading Subtitles & Maximizing Causes Terrible Screen Lags

[ssdevious]

1 thing actually improved, I have my sound back, but the video is still choppy, when maximized and with external subtitles loaded in.

Funny thing, a friend of mine, who has also these problems, but unlike me, he keeps old releases of software sent me his 2.43 and it works just fine with EVR, etc.

What was so radical that changed between these versions? I mean, there's a lot of stuff which changes I guess, but I believe the last version working fine for me was 2.57, then just something went wrong.

Any guesses? Or should I try to browse for more codes, perhaps focus on those, which goes for .mkv, I also don't want to screw up my PC more then necessary.

Thanks,
