64 Bit Causing Lag!

[Mak4thRyder]

Hi, i've tried to find a solution to a problem i have been having but it
has been fruitless uptil now, hopefully somebody here can help me.

Recently i updated to Windows 7 (Ultimate) 64 Bit, to get rid of the
3 GB RAm limit on 32 Bit, as you can guess before it was 3.00 GB Usable
now it is 3.87 GB usable, everything works fine but there are a few problems.

My system specs are,
Core 2 Duo 2.6 GHz
4 GB RAM (3.87 Usable)
Nvidia Geforce GT 220

I know my "rig" isn't all that much but it runs the games i want it to run, atleast it did.
Since i updated to 64 bit, certain games are lagging, GTA IV lagging to much,
Spec Ops The Line lags, reminder these two games did not lag before, but they are
lagging badly now. While on the other hand certain games are running smoothly,
no lag or anything .. So why are the games which used to run perfectly before on 32 Bit
lagging now? while others are running without a problem, any help would be appreciated.

Thanks.

I'm going with a bad pirated copy of windows. No one in their right mind spends $200+ on a copy of windows for a machine that old. You need a known good copy of windows, meaning store bought, and then you can worry about debugging.

With 4GB installed it is fine being on 32bit which is really the limit. On 64bit it is recommended to have 8GB.

Can someone give me a definitive answer to what options do i have? downgrading to 32 bit would make the extra 1 gb ram useless or
is there any other way to get rid of the lag?

The "bitness" shouldn't matter. I went from 32bit to 64bit and had no problems. (rig even had 4GBs at the time, so not sure what Rolli is claiming.) I'm still guessing you have a bad copy of windows. Probably has virus in it and that's causing the slow downs. A clean/good copy of windows should run just fine. (assuming you aren't having a temp problem or something like that.)

OP can always check if he is running out of memory http://lifehacker.com/5415355/do-you-really-need-more-than-4gb-of-ram note the article is 5 years old and it was a discussion then.

My copy of windows is legit, can you guys really clarify why those games are lagging? I mean if there is going to be
lag it should be in all games, right?

Some games use more ram than others and with extra overhead now on 64bit OS you may be just hitting the limit.

So uhm what do i do? how do i fix my problem?

 

[rolli59]

If you are in fact running out, how to check in my link earlier, add ram.

What's probably happening is the OS is using more RAM for normal operation, leaving less free for games to use. As a result, you are seeing more paging, which is dominated by HDD performance and KILLS in-game performance. That's why 8GB is considered normal for 64-bit systems.

You can use the Performance Monitor to check this; check to see what RAM usage looks like, and how much HDD activity is going on.

RAM usage shows as 1.38 when using firefox with vlc in the background, how do i check hdd activity?
