The soul calibur and all of your uber weapons lag me.
Then get a computer that isn't 80 years old. You can build a desktop for around $270 that uses an AMD Llano A-Series. These APUs have extremely good graphics modules. My laptop has one and it can run loving
CRYSIS 2 at reasonable speeds. I get 500 FPS in Blockland, constant.
And hell, that number isn't the lowest it could be either. If your current desktop(should you have one) uses an ATX form-factor motherboard you can use its case, PSU, HDDs, monitor, keyboard, and mouse. Then you're only paying for the Motherboard, CPU, and RAM, which is only $128 with shipping. If you really wanted to you could cheap out on the RAM (2GB instead of 4) and drop the price even lower.
I understand that you may not have the money, but that doesn't mean you can't save up for it. And it CERTAINLY doesn't mean you have any grounds to complain about slowdown from my Add-Ons. Hell, I'd even put the thing together for you myself if you would just shut up about it.
