I was playing league of legends yesterday just fine, 144fps gsynced all that.

Today I play my first game and my fps fluctuated between 80-144.

Anyone know how I can troubleshoot this?

A memory leak is when a program does not free up its memory. This is only a possible problem if the application is long-running or if the operating system does not free up the memory after the program has ended. Since all modern desktop operating systems most certainly free up the memory after program exit, it's definitely not the latter. You're saying you just played your first game, so it's not League of Legends that is leaking memory, unless it's leaking memory right from the start.

To actually diagnose a memory leak in Windows, simply open up the task manager (ctrl+shift+esc), make sure you're in "More details" (check the bottom of the window), go to the Processes tab, and click on Memory to sort by memory usage. If your memory usage is not even close to 100% usage, then memory leakage is not a problem, but you can check to see which programs are using up lots of memory (potentially due to leakage).

Awesome, we have a pc god. I did some snooping and found out there are twitch streamers also reporting a fps loss. What's interesting to me is that they reported losing more fps as the game goes on (games last 30-45min) but my fps loss was apparent from the start.

My ram sits at a lofty 35% even with google open. I've yet to try other games to see if it's the os. I ran memtest64 for like 15min but don't know what to do with the results as I've yet to google it like the guy above said. Also not sure if 15min was enough to diagnose anything as I turned it off to be able to use my pc.

It's common for frequently updated games to attain memory leak issues when there weren't any prior. Blizzard is notorious for this, though they usually fix it within 24 hours.

Are you playing windowed? If so something else might be having frame rate issues (browser, etc) and the game is syncing to that frame rate.

Otherwise, look for anything that could be affecting frame rate. Things like Slack or keyboard software (Logitech, Im looking at you) do weird things that will tank frame rate randomly. Try close everything while watching frame rate to find an offender.
