I have an Acer Aspire V15 Nitro with a very powerful i7 processor and nvidia 960m dedicated gpu. I have been having a lot of problems lately with source engine games such as CSGO and TF2, where I get very low frames down in the teens. I would say on average about 17 fps. I am pretty sure that the game is using integrated graphics to run the games by default (windows 10). Every time I try to change to the more powerful graphics in nvidia control panel, it doesnt change the performance at all. I was playing csgo and tf2 at about 150-180fps on sunday, now all of a sudden I am getting no more than 20fps. I just did a fresh install of windows 10, and all drivers are up to date. Also, It is not in power saving mode. I checked that. Any suggestions?? Thanks...
