a question about progress

Emulating a system such as playstaiton 2 has got to be a pain in the arse.
Specially how the system works, it has 32 megabytes of ram and a 4 megabyte graphics card, now think about how much data must be swapped in and out of memory for a game like for say grand theft auto, or final fantasy 11 mmorpg , the ps/2 has a massive memory bandwidth(direct RDRAM connected to the cpu) to compensate for the low system ram. Now i'm sure the game programmers who optimized it made it so it could utilze high memory bandwidth and data swapping.


Now lets look at PC's i know that i have ~12gb/sec thuput of memory bandwith on my opteron workstation with the onboard memory controller of AMD64 based procerssor. Now the average pc, for say an athlon xp or athlon MP, has about 3gb/sec two way memory transfer rate, and 6gb/sec 1 way.
In order to make the ps/2 emulator work on average game pc hardware is going to be prety tricky alltho i could see caching alot of parts of the game into ram on the pc transparently without the game knowing it so it can be faster accessed , i havent really looked at pcsx code so i dont know how it works but im just posting this to show part of the delema the programmers are facing and hopfully it makes people think about it.


Also , incredible work guys .8 will be a very fun release to play around with. Its better to wait and let things get worked out than to be impatient and then be disapointed.

i can see that the team is working hard on the graphics issue.
but it seems that the speed is not improving. why does the team works on graphics only? (or not only, i am just asking).
if you want to please the crowd why not work on that too? or work on it more? (i am not attacking anyone so don't take it perssonaly).

speed has improved tremedously already, why ask such ridiculous questions, pal, do a favour and be patient, this a'nt the first emulator that has taken time to complete. Look at PS Emulator. Became no.1 after a lot of dedications and hardwork from the EXPERTS. The team works on graphic first because thats what need to be done first. As said by boistman [Because you first do accurate emulation,then optimise speed.]
no one else is asking because they already appreciate the speed in which the Emulator is progressing. Everyone wants to see it all done.
It looks like your the only mouse out there whos not pleased (sorry for mouse, its just a figurative way of speech). the team had worked already hard which everyone should be grateful for and should be congratulating the team that PCSX2 has made it this far because of their dedication. (i'm not attacking you too so dont take it personally)

PCSX2 :guitar: Rocks
Continue The Awesome Work

Buzz Off

Besides that Linuz and the other guys hardly gets time to make the emulator. I read that Linuz usually does the coding in the weekends for a few hours

To your question about progress, the answer is that , according to linuz that he is "working on compaitability and speed" like Cloud said, they can only one thing at a time and also, linuz says what we would find new in PCSX2 next beta version is improved speed, compaitability and PS game compaitability. The team is working hard and since they work on their free times which happens to be around a couple of hours per week...............

Anyway, you'll see better speeds, better compaitability and other functions available once the EMU is finished or rather in the next release

The two years legacy has brought the team this far, they can work to better fields if you guys dont poke your noses too deep about compaitability and speeds
