I've just got a new computer up and running and was setting up Dxtory. Part of the reason I've built this new PC is to record games so I can keep clips as mementos, etc. so I went out of my way to get proper hardware that can handle that not just on the gaming end but also a 7200RPM, 2TB hard drive to actually able to record HD @ 60fps.

Now, I've set up Dxtory and installed the Lossless Lagarith codec, the codec I've used on my previous, a bit less powerful PC to great results. However, when I go in-game and try to record at 60fps, Dxtory reports the record speed to be fluctuating around 25.5 - 24.5fps. Indeed when I go to view the resulting video, it is choppy and sometimes plays back at even less than 25fps.

The Dxtory benchmark for the hard drive I'm using is 193MB/s, which should be enough (1080p @ 60fps purportedly requires ~110mb/s and I'm well above that.

I'm really lost as to how to proceed from here on. Anyone here use Dxtory and could help me out?

Don't know where you got that from. There's no set rule of thumb on exactly what is required to produce 1080p60 because it depends on the game, your game settings, and in DxTory, how many drives you use to write the capture file.

The only way I ever use DxTory is by using at least 3 HDDs to write the capture file. That way you get much better performance in game. Unfortunately for you though, that also means you can't use Lagarith. The only way to use DxTory's Distribution Writing feature is if you use their DxTory codec and set output file type to RawCap instead of Avi. You then have to merge the RawCap files into an Avi using their RawCapConvert tool.

Lately I do most of my capture with ReLive, because AMD finally got the shortcut hotkeys to save the Instant Replay file, and it seems to be working properly now, save for some Mic distortion if you want to record mic sound. If you're on an Nvidia GPU and want best performance, I suggest using ShadowPlay.

Easily equal to that of ShadowPlay. Another trick if you plan to upload 1080p vids to YouTube , is to run them through a tool like Avidemux when you edit them. It will edit frames, compress, and resize. Now here's the trick, if you resize a 1080p clip to 2048x1152, YouTube will use a higher bitrate to convert it.

Because it's the next available size up in 16:9 that only increases pixels by 7%. Too much increase in size would cause too much blur. But when you only add that many pixels, the added sharpness of the higher bitrate YouTube uses for that res easily overcompensates for any slight blur with increased pixels. Thus you end up adding more sharpness than blur.

That said, with any 1080p upload you must also make sure you use high enough bitrate yourself when capturing and compressing the vid.
