My current systems spec is a:

Athy 64 3200+ SKT754,
256MB DDR400,
PATA133 60GB HDD
256MB GEFORCE FX5600

It seems to be running Americas Army extremely slugishly and the load
times are unbareable.

And the cpu and hdd is being unduely hammered for sure.

Honestly Ive seen a Athlon ThunderBird 1ghz load it *MUCH* quicker
with less drama.

So Ive been wandering how 32bit IO is affected under 64bit..

Hi.

While the 256 MB Geforce is alright, the 256 MB RAM is not, in my opinion. I
don't know the game, but with such restricted RAM resources you should maybe
not expect it to perform as well as it would on a 32bit system. Honestly,
256 MB sits in a SD Card in most cameras today - if you mean to do serious
gaming in 64bit, you might be alright with 1GB. I would aim for two, though.

But the I/O question is interesting since many, otherwise well informed
people, tend to forget that a 64bit data path is not one bit faster than a
32bit, unless the 32bit is already filled up. It's like a freeway, doubling
the number of lanes on a stretch of road will not pass through more traffic
if it isn't full to begin with. If it is full, the extension will only reach
it's potential when it becomes full. So, this is really not the important
thing here. You are sitting with the extended freeway and a single lane
entry/exit point. The important thing is what the OS can do with the
registers of the 64bit processor and the amount of RAM that it can address.
And this is your problem - the system is so fast that there is rapidly
nowhere to put all the data that it processes, your graphis card is
screaming for data and your HD is trying hard to deliver, but it beomes a
bottleneck because of a lack of total system resoures, which in your (case)
crystalizes into 'RAM'.

This is my opinion, others may think differently.

Regards, Tony. . .

Thanks for reply tony..

I put 512mb in the machine and updated geforce/nforce drivers *yet
again* and hey presto... load times are down to 8seconds and in game
performance a happy 30+fps with reasonable settings...

The 77.x gf series drivers I was using also supposably had issues...
Now using 81.x
Do any gf drivers not have bugs these days hehe?

I agree with your analagy, when a 32bit program runs by the way its
executable (code) is compiled, the on ramp and off ramp isnt even gona
be big enough to get the traffic on the extra lanes.. with out slowing
down the bigger picture.. anyway

Quite! My experience is that most of the time you don't really need a
speed-demon, unless you have far-out needs. It's a kind of an art to balance
the total resources of a variety of quality parts, if you succeed, you'll
end up with a very stable machine that is slightly slower and slightly more
expensive than you hoped, AND that you will be happy to live with.
