I changed the resolution to the amount that you suggested, and I also changed the Refresh Rate to 60, and oddly enough, these changes seemed to help.
However, it didn't stay that way for long.

I'm guessing by this point that there is probably no fix for my issue, and that I'm just gonna have to deal with it.

@ManeEvent4U2 Unfortunately, you're probably right. As I said in the beginning, your system is under the recommended specs to play TS3 and most of its packs. Different players can get different results from the same hardware, but there's only so much you can expect from an integrated card.
If I didn't mention it before, you could always try Windowed Borderless Gaming to see whether that makes a difference. It might not, but the program itself is easy enough to use, and popular among TS3 players.

I tested it out just like you suggested, unfortunately, it didn't do anything to help. It really sucks that I can't seem to find a fix for this :/ Oh well, hopefully we get a new graphics card soon.
Thank you so much for all your help, I really appreciate it!
