back in 2014 i was able to play in the same pc i'm playing today, at 1080p in high settings, but since i returned, in the end of the last year, i found a lot of new problem with the gama frame rate, and i've been able to run much graphical demanding games in the same machine.
recently i quit playing at 1080p and decided to go to 720p low or 480p medium, and it got a little better. meanwhile i ordered more 16GB of ram and a SSD drive, that i may receive next week, to try to make it a little better.
i don't care much about the graphic aspect of the game, i don't mind to play at 720p low or 480p medium, but i can't stand playing at 10 to 20fps, i really hate it.
the weird thing, is that in the last days, i've been noticing, that after 1am, until about 5 to 6am, i can in fact play at 1080p in high settings at 100fps, but, right now, at 8pm i'm playing at 720p low getting 20fps.
how is this possible? how can this be related with my system and how can i fix it?
