In the past few weeks, and in particular the past few days, I've started to notice some pretty bad lag spikes in GTA V - both with and without mods installed. At first I thought it was due to a memory leak, since they only begin to happen after some time of playing and continually get worse, and because I only have 8GB of RAM. But after watching my resource usage while playing, it was the disk usage that seemed to be directly linked to my lag spikes.

These usage spikes occur on my C: drive, and correspond with the stuttering (the audio cuts out as well) I experience in-game, but the game is installed on my E: drive. My NVIDIA drivers, however, are installed on the C: drive, since they refuse to be installed anywhere else. Could that be the source of the problem? My C: drive is also an SSD (the E: is a 1TB hard drive).

Lastly, I only began experiencing these lag spikes after I reset my PC, but I had everything setup the same way before resetting. I do not experience this with other games.

What should I do? Tell me if you need more information from me to get a better understanding of my situation.

I had the same thing happening on my old PC. I fixed it by opting for a 4gb gpu and 16 gigs of ram. Runs like butter now.

Or, if you have an NVIDIA Card, try going into NVIDIA Control Panel -> Manage 3D Settings and then changing Shader Cache to 'Off'.
The above brought me from 40FPS to around 55FPS

It could be from overusage of memory though, since that'll save on the pagefile, usually on the C:// drive.
