I recall having a similar issue until I had to install DirectX 9.0c even though Windows 7/10 already had a higher version of DirectX.
You can find the downloader by doing a Bing search for "DirectX 9.0c installer" and finding a Microsoft link.
Yes, I said Bing, you're searching for a Microsoft download so Bing. Whatever else you might say about Bing, it is good for finding stuff on Microsoft's site.
oddpastry: I have a pretty good computer and the game has ran fine before but i recently installed the game and its chugging really bad when people move, whats a good fix? I saw a lot of people say restart your computer but ive done that and theres still the issue.
olnorton: Restarting you computer doesn't work if you have fastboot enabled.
Unfortunately somewhat true, however you can force it by entering a command prompt (cmd) and typing "shutdown /r".
Alternately use the "run" command, invoked by holding down the Windows key and pressing R.
You can also use shutdown /s to turn off the computer, so long as you don't use /sg.
