 Hi, log this on the MADVR forum, there are a few issues that could cause this, people will want to know what CPU/GPU and windows versions etc you are using and you settings.  

I've just registered there and have to wait 5 days before I will be allowed to leave a comment :\
I've investigated the issue further, checked the frame stats with and without subtitles - I see no difference in numbers at all, but there's huge difference in playback smoothness. And there are actually no dropped frames, the playback just looks as if there are lots of them.    

first thing to do is rule some stuff out, do you have the same issues when playing the movies in MPC-HC or MPC-BE, if so it might be LAV filter issue, hard so say but this has been disccused quite a bit on the fourms but sorry, I cant remember if it was MADVR, LAV or DS forum. Do some searching.  

Users on the madVR forum have supposed that the issue could be due to XYSubFilter and suggested disabling it. It's too radical solution. Is it possible to replace XYSubFilter in DSPlayer to another subtitles renderer?
