Dxtory Recording FPS is lower that the Game FPS

[DarkPhoenix]

Hello to anyone who might read this. As you can guess, I have a bit of a problem at the moment. Dxtory used to be working fine for me. No problems or anything. I recently started having a rather annoying issue, though. Whenever I would try to record in Dxtory in certain games (Skyrim and Stellaris, though Stellaris was less so, to name a few), the fps the game was recorded at would be well below that which the game was playing at. I have Dxtory set to record at 30 FPS but the recording Frame Rate can go down to 15 FPS despite the game running at around 29 or 30. If you can help me resolve this, I would really appreciate it. In case it helps, I've included a list of my PC specs and Dxtory settings below. I hope someone can help. This is really annoying.

Your HD write speed is likely the bottleneck for a lossless codec at 1080p.

On my system, a static image played at 1080p 30fps requires about 60-70 MB/s to encode with Lagarith in RGB mode.

While your intial post gives some information, a full environment information will be needed for better assessment: http://forum.exkode.com/index.php?topic=2.0

It is most likely your HDD, Dxtory's default codec is not the best at compression. You can try MagicYUV or UtVideo.
