Hi there, I'm using OptiFine for a long time now and I've usually only used it for the zoom in with Ctrl, now I want to play in but it's always the same resolution no matter which one I use ( 1600x1200 ) . This worked in 1.5.2 since I liked messing with the options and making everything look even better than all high settings. I really need help with this, :/

If I had to guess, there is probably some sort of config txt file related to optifine you're going to have to change it in manually.
