Hi, im Hassler, this is my second post in Minecraft Forum. I have a trouble with Minecraft (vanilla), so, the last week i played minecraft normally, i played minecraft at 80-200 fps in fullscreen and with 640x400 of resolution, but recently i change my operative system, i had Windows 7 but i change it for Windows 8.1 for some problems. When i install Minecraft in Windows 8.1 i look that i can not put minecraft in fullscreen, because when i put Minecraft in fullscreen my pc screen begin to flashing and appear some white lines thath through the screen, and it put some laggy, (1-30 fps) so i'll to put minecraft in mini screen (window mode) but in miniscreen my minecraft get 1-30 fps, so bad, and i can not play there.
So, my problem is that i need to remove the flashing in fullscreen, just in fullscreen and put the resolution in 640x400 in-game: Options > Video settings > Other > Resolution > 640x400, because now, when i've Windows 8 dont appear the resolution 640x400, appear the others, 800x600...1024x720... but not appear 640x400 and i need it, maybe the operative system affected it? Windows 8, because when i had Windows 7, the resolution 640x400 appear! now with Windows 8 not and i need remove the flashing when i put fullscreen, Thank you for read, and i wait yours answers. Sorry for my english, but is not good i naturally speak spanish, if u dont understand contact with and i'll put this in spanish, ty.
