i dont want to buy a OTHER GRAPHIC CARD >:(
No offence, but when you're trying to play video games on a computer with a freebie graphics card built into the CPU, you can't expect much performance when the industry standard cards are about $100. I know Blockland is not exactly extremely demanding, but come on.
That being said, I also have an integrated GPU, and while I can only run minimal shaders, I love the performance increases in the recent updates, and hope to see more in the future.
