Microstutter [No Paging] (Resolved- Cause: gametime.maxvariableFPS)

 I've been trying to get back in to Battlefield 4 lately with the release of Dragon's Teeth but I've been having a HUGE amount of microstutter across the board. Trying to determine what it was, I looked at page file use (though it shouldn't because I'm on 8GB of RAM here), GPU performance problems (which doesn't really make sense since the same problems happen even on lower framerates), and CPU overheating but it's always been behaving around 75-80c.

BF4 runs on an SSD. Page File is on a secondary HDD but at the same time, I can't exactly tell what's causing these problems.

(The odd resolution is a result of monitoring memory usage out of game.)

Can someone shed some light on how to read the performance graph so I can know where to start looking? As an aside, it seems that these stutters seem timed in with audio queues, not sure.

    Not quite. The stuttering was much more frequent and much more harsh. That said, I've managed to fix this myself.

    This issue is now "Resolved" 
    -------- 
    gametime.maxvariableframerate was the culprit. A reinstall of the game removed my existing USER.CFG which reset the game to an uncapped framerate. It performed admirably, though the framerate was far too high for what I needed. When re-enabling gametime.maxvariableframerate, the spikes returned regularly. This may either be a bug with the framerate limiter or perhaps it wasn't intended to be used in this scenario. Either way, I'll be finding another option to limit my framerate.
