Okay, I had this problem since only Yesterday. Firstly my video game performance unexpectedly and suddenly dropped. I Don't know what caused it, how and why. Other games were still working fine WITH The 2D ONES and LOW3D 90's Games. But performance Games such as Battlefield 4 and FH4 which i play at LOW Graphics began to degrade. I USED To play them at 30-35 fps FPS the day before the problem started but now, it degraded into 15-20 fps when I try play them again after I woke up in the morning which is so unexpected. The fps only runs SMOOTH If you're on a game menu, or looking up to the sky, which is the case for those weak Graphics card, but in mine it always used to run these games VERY SMOOTHLY EVEN IF you are looking at certain places that render and load a big chunk of textures and graphics until this problem occurred. I know overheating is not the issue because I barely play my laptop during Weekends and let the device have a 3 day rest from time to time also, overheating comes only in a period of time but in this case, the problem already exists even when after I just booted my computer. I have found no malware, viruses, spyware or any kind and since I think these don't affect the game performance and only software so i don't really know whats the problem. I don't know where to post this question if it should be the laptop support forum, video card forum or other hardware forum but all i know is that I hope someone could help me what condition my laptop is facing and how to fix it. It would be gladly helpful if some people did so.
