Help! GTX 560 2GB Less Than 30 FPS in Minecraft

[FB1Productions]

I have a GTX 560 2GB OC with a i5 3570K @ 4.2Ghz

but in minecraft I only get 24 FPS. It seems like it's locked at 24 FPS. It only gets locked at 24 FPS when I go 1920x1080. When I pull the minecraft window as high as it can get and about 1 inch from the side of the screen on each side (27" diagonal monitor) I am still at 400 FPS as it was when it was smaller. But when I pull it those inches on each side my FPS drops to 24 and stays locked there.This issue isn't due to switching to the integrated graphics because my GPU usage goes up. This has just recently randomly begun to occur. Anyone know a solution?

Again, its a monitor and as far as the nVidia control panel says, its running at 60Hz

change everything to max video settings then click save, Then go back to video settings and look for the TAB labeld Performance it will be on power saver change it to MAX FPS I wont alter the quality it is just a power usage feature for your graphics card with performance mode on I get no more than 35 FPS with it on MAX FPS I get 8759FPS this game runs on fresh air basically XD
