Recording always drops to 24-25 fps (1080p)

[apo]

When recording with dxtory at 1080p, the frame rate always drops to around 24 fps when with any codec at 1080p30. I primarily tried with Lagarith. With FRAPS, I can capture at 60 fps with no frame drops.

This is when recording to a separate 7200 rpm drive. Even on SSD it still drops to 24 fps. No other capture software I've used has had this kind of bad performance. I figure I set it up wrong, but I have used the same configurations as others.

Edit: this only seems to happen with a few games, such as The Walking Dead by Telltale Games and Mass Effect 3, both get stuck at low 20s when recording. Other games such as Left 4 Dead 2, Battlefield 4, etc. work fine and record at a constant 60 fps with the same settings. I guess it's just an incompatibility of dxtory with certain games.

It will be normal operation that FPS is limited, if a "Synchronize Video FPS" option is used.

[apo]

The games can run at 144 fps when not recording. I set recording frame rate to 60 and sync video fps to prevent stutter in the video. Some games record at 60 fps perfectly, other games the video cannot go above 23-24 fps, even though the games are not demanding at all. I recently upgraded my video recording HDD, new one has 205 MB/s write speed according to dxtory benchmark, but still the same problem. Happens with both dxtory and lagarith codec. Since most games record fine, it must be some compatability problem with a few specific games and dxtory.
