I have VLC 2.0.7 and I got micro-stutter per ~0.5 seconds with or without reading subtitle (TXT) in Direct3D running XP x86 SP3 while I got micro-stutter with reading subtitle (TXT) running Win 7 x64 SP1. No micro-stutter at AERO enabled but yes at non-AERO
HELP...
NOTE: I got no any micro-stutter in DirectDraw both OS' (but less micro-stutter on XP) but DirectDraw is images dirtier than D3D.
ADDED: No stutter at aspect ratio default/auto but I changed aspect ratio and appeared stutter.
My PC:
i5-2500K, 8 GB DDR3-1600, GeForce GTX 480
