I was trying some games like ROBLOX, CS Portable etc. and the fps were better than in the other laptop, but when I wanted to try minecraft, I was going to a dirty amount of fps, in addition to many white spots that make it look uglier, I have already installed the optifine, I install java 7 and 8 64 bits and I tried each one separately and updated the drivers but still very bad, the optifine configure as minimum as possible, but I have not noticed much change, they have only gone up as 4 fps! please help
I have a friend with a laptop that has an amd c-50 1ghz processor dual-core with 1gb ram, and the average of fps is 30 - 40
amd radeon hd 6250, and on my other laptop runs well, so I do not think my laptop can not run minecraft
here a video with the graphic card running minecraft:
Try disabling all other apps and internet when running it, and decreasing graphic options in-game from fancy to fast or max to minimal. I had similar issues before and those were the only things I could do to fix it.
