Hey, I have a pretty decent computer, but when I record Minecraft with fraps at 60fps I get lag spikes, even though I am locked at 120 fps on minecraft...

Here are my Specs:

CPU: Intel(R) Core(TM) i7-5820K CPU @ 3.30GHz (6cores 15mb Cache - Can overclock to 3.8GHz)
GPU: GeForce GTX 770
RAM: 16Gigs
Operating System: 64bit 8.1
HDDs: 128GB SSD 6Gb/s Main + 2TB 7200RPM SATA 6Gb/s Storage

Fraps is installed on my HDD, and recording to my HDD. My CPU isn't overloading at all - I'm also on the latest java. No exceeded ram is allocated to fraps or minecraft, just default.

As a little pre-post disclaimer: I'm not much into gameplay recording, so I'd wait for someone more experienced than me to confirm/correct what I said.

Feels like an HDD bottleneck to me, due to how fraps works. While java loads most stuff in memory, if it has to access a file on your disk, it'll ordinarily read from it, and only load it in memory if the original developer planned so.
If the disk's buffer is, however, (almost) completely taken by fraps writing uncompressed footage on it, it would make sense the game (or any other software) stutters.

Have you tried other solutions? Such as Shadowplay or OBS, for example? They compress video data on the fly before writing to disk, sensibly reducing the load on it and leaving other apps more breathing room.
