Delay in everything in GMS

Actually Tri-Buffering is a recommended ON setting for many games and messing with pre-rendered frames can actually create graphical problems like tearing and frame skipping.

3 Frames is the default setting for most graphics cards, leave it alone.
Tri-Buffering uses the default 3 buffers to create a series of frames swapped per second. Modern PC hardware runs fast enough for you to even notice this. It actually can help the graphics run smoother and faster in cases.

I would look at System Services you have running that can be Disabled or set to Manual usage. One service is very problematic... Hard Drive Search Indexing. Turn it off and you'll have less wasted resources so the system runs mainly for what you have. Try also using a lighter weight anti-virus like Microsoft Security Essentials or Avast Home, if you have one that uses a lot of resources just for scanning. There are tons of things you can do just on the system to save resources.

Also check your internet connection. Switch from using connect on demand to always connected for how your router works. Read up on how you can optimize your local network even at home as well. Often it can be simply using better cabling like CAT5e or better.

Look also into seeing if you have any unwanted software running on your PC. Viruses and malware cause PCs to run slowly. Scan your system and see if there is anything causing problems.

I know what the problem is now.
