I'm having problems playing games due to large lag spikes. I'm worried about this now because I don't want to have the same problem when I get a real GPU later this year. Right now when I play Just Cause 3, by adjusting the settings I can get 25-30 fps, but every so often it will just dip, usually for long periods of time. (Note: this can happen at any time. Sometimes it happens during instense action scenes, other times it happens when I'm just driving a car). Here's what I do know.
1. MSI AfterBurner claims I'm using about 1800 MB of vram, even though my card only has 1 gig of Vram.
2.Every time I get one of the huge lag spikes along with it I also have a huge increase in disc usage (usually up to 100%).
3.My Ram usage is at about 7 gigs while playing Just Cause 3, but it seems like I still have about a gig of free ram. (I have 8 gigs of ram)
4. Every time the Disc usage spikes the graphics card usage dips way down. (Along with the frame rate).
Everything I've said I have screenshots for to show you what I'm talking about. If you need any other specs of the computer don't hesitate to ask. Again, I don't really mind that I can't play games right now, but I'm worried that this is an issue that will effect me in the future. Vram Usage Gpu Usage (Notice the dips) Gpu Stats Disc Usage Over a 60 second time span of playing (you can also seem ram usage here)
EDIT: After doing a little bit more research it looks to me like I'm running out of vram, and because I'm also using most of my system ram, it is paging to the hard drive. This would explain pretty much everything, but I'm not sure if it's true, so if anyone could confirm or deny this it would be great!
