MTA Fullscreen issue

[Durock1]

I'm having an issue with MTA thats been bothering me. Basically, whenever I go on MTA it doesn't seem to go fullscreen despite it being on in the MTA options. And how I know this simply because i've been getting random small fps drops when ingame, which never occurs when im in fullscreen. It is sort of like in a fake fullscreen mode and ive got no clue how to fix it, can anyone help me out? I've tried re installing, using a different copy of GTA:SA to install MTA and nothing seems to work.

I realized that this was a normal occurrence on any game that I've played, I'm just having fps drops on certain servers that I play, which should not be the case since my PC is very good. Here's my MTADiag Logs if anyone can help me with these fps drops: https://pastebin.mtasa.com/965173837
