I'm late to congratulate u but still 2k elo is a really good achievement!! You are qn inspiration.
What does your name mean? Not trying to be offensive but did u know that in Spanish Tocacaca is literally the translation of poop-toucher?
Were you watching a replay on this ss? The game consumes ~2400MB of RAM for me right after I open it up. I don't have CaptureAge installed but it doesn't seem like it's taking a high amount of RAM usage.
Deleting some replays and saved games might improve the performance. If not...
I've been trying this recently and it has helped me a lot with the tiltness my ELO drops but I think I learn something new and even use more hotkeys now for some reason so there's some improvement.
Once you get more practice you can get some pros guides or study more, we're blessed...
