Dxtory Recording FPS is lower that the Game FPS
« on: November 21, 2016, 11:17:45 pm »
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.

Computer -

AMD FX 6300 3.5 GhZ Processor
Gigabyte GA-970A-DS3P
16 GB Memory (7.97 Useable)
XFX RX 470 4GB Graphics Card
Windows 10 Home Premium Operating System

Dxtory Settings -

Write Speed: 50 mb/s (the benchmark put it at about 60 but I bumped it down a bit in case that was my issue. It wasn't but still...)
Codec: Lagarith Lossless Codec (64 version)
Frame Rate: 30 FPS
Recording Resolution: 1920x1080
Synchronize Video FPS: Active
Scaling Percent: 100%
Audio: PCM 48000 Hz 16 Bit Stereo
Thread Priority: Normal
Use Default Settings: Active (All other options under the Advanced Settings Tab are off)

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.
