Hey,
I have had this PC for about 3-4 years, Nvidia GTX 1070, i5 6500 3.2 GHz.
It has been working great. I recently bought the new Modern Warfare and have been experiencing extreme FPS drops to 0 fps and now even with every setting on low, the low fps and inconsistent fps makes it unplayable. IDK what the issue would be. I do not play on a very good monitor so it may be that, or the cpu or even gpu. I have no clue and was hoping for some help.
