i want to run a ps2 emulator
but my fps suck incredibly.
my computer is a compaq presario (gift from my dad)
it runs windows 7. its ultimately slow as fuck.
thats pretty much all i know about it.
dont even know what graphic card it has.
Sure you'll be able to at least run it, can't say much about playing anything.
Why not try?
When I ran it like two years back I was running off a Radeon 5870 and a GTX 260 with a quad core 4.2 or something Ghz CPU getting full FPS on any compatible game. Unless you have some top of the line laptop, you will not have much luck playing them, but you can try disabling Anti aliasing and other options that cut into performance if you really want to try.
OOOH! I HAVE AN IDEA.
You should get a job so that you can get money so that you can upgrade that shit!
You can also download the PS2 system data off the PS Market for free.
When it comes to emulating, I believe there is more emphasis on the processor as compared to the graphics card. It doesn't take a great graphics card to render PS2 tier graphics.
Game Booster might help some. Sorry, I am not much help for anything other than photography. e_e
Compaq is still a company !?
Oh god, lol. Also, newer computer is the only way. If its an off-the-shelf computer its probably a microATX sized case and motherboard, so you won't be able to upgrade like anything lol. Your best bet is to start building from the ground up. New case, CPU, GPU, RAM, Mobo, PSU, heatsink, and whatever else I'm missing.
How much ram are you running the machine with?
You probably need around 2gb ram and a 3.0ghz processor to play at a decent frame rate.
compaqs are horribly un-upgradeable. they usually have a pci-e expansion slot, but it won't be able to fit what you want. trust me. check out the innards and check before you buy anything.
Better solution.
Buy PS3 > Buy SKU Flasher > Hack PS3 > Run PS2 ISO.
