Pentium D = Speed Hacks?

Ok, My system is....

Intel Pentium D 820 2.8GHz @ 3.6GHz
Asus P5WD2 Premium WiFi-TV Edition
Corsair XMS2 DDR2 675 PC2 5400 1Gig
WD Raptor 76.4Gig 10.4k rpm
XFX 6800 GT 256Mb GDDR3

So, knowing this, and that I'm running Windows XP Pro SP2, When I play games I get inconsistant game speed. What I mean is that in GTA: San Andreas I move very quickly indoors(in small areas) and when I look at the ground...Also in CS 1.6 I have been accused of Speedhacks and have justly incredible speeds....however I am not hacking. I beieve it may have something to do with my SMP settings or mearly the fact that I am running Dual Core...It seems the games are getting ahead of them selves...I know I sound crazy but Do any of you have similar experiences, thoughts, or hopefully an explination?


Thanks
 
Since the games are single threaded, the Pentium D won't "double their speed."


Then again, I really can't believe that that's happening.
 
Yeah, its something with your overclock and the NIC card sending packets.

That doesn't explain the single player game's faster speeds that he reports.

O, didnt know it was in single player- Reinstall windows is ure best bet IMHO

if it bothers you that much, just lower your damned overclock. i think i would want the faster play, but that IMO.
 
I have the same problem with my X2. It seems to be an issue game not liking the dual cores. I found a temporary fix that worked for me... Start the game, then alt-tab out, then set the affinity of the game to run on only one core.

Works for me, hopefully it will work for you.
 
Ive heard of this problem before though, prior to all this dual core business......Maybe it was on a dual Opt. or Xeon system :p

I think you missed the point.....He is being accused of hacking...I think thats the part that bothers him


Or maybe I missed the point :)

lol, just say that you have a dual core p4 running at 3.6ghz, im sure they'll understand ;)
 
Yeah, I have: 1). Reinstalled windows... and 2). tried to set affinities, but I am thwarted with the error: 'This operation could not be completed. Access Denied', and 3). I have turned off all of my Overclocks... I have looked into the bios and no luck either...

Nearest I can figure the game calculates real time( the time it takes you to take a step) by reference to the clockspeed and how long an operation should take...but some how windows or my mobo are 'overpreforming' and skewing the relative time. anyways waiting for more help...
 
I never saw this on my Dual Xeon system, but I have on my X2 a few times seen GTA:SA go into some weird hyperactive mode like he describes. I restarted and everything went back to normal.

A loose theory would be that, due to your overclock, the power management kicked one core down to a lower clock for a period of time, and thus the RDTSC clocks got out of sync (RDTSC increments once per clock cycle). GTA:SA is possibly assuming that the value returned by RDTSC is consistent no matter what thread it is calling from.
 
My friend had this happen to him on his laptop. It ended up being caused by the intel speedstep technology. He turned it off in the BIOS and everything was fine after that.
 
yeah, speed throttling seems like a better explanation than dual core. Both AMD and Intel employ this (though intel far more heavily).

I find it hard to believe that the 2nd core is having any impact upon the game, simply because the game isn't programmed to use the 2nd core. Though, given the feedback in this thread on similar issues with SMP setups, I can't say for sure what is happening.
 
I've done some programming and my games have run into the same troubles.

I'm pretty sure it comes down to the timing code in all game applications.

We use the "QueryPerformanceCounter" function which returns a 64 bit number which indicates the number of CPU cycles (or something of that sort) since the boot of the computer.

However, I think sometimes you call that function it hits CPU #1, other times it hits CPU #2. Since the number of CPU cycles are different per CPU and are not syncronous, you can get some major stuttering in games and other odd behavior. The only way to fix this is to put all the timing code in a single thread and place that on 1 CPU... Or force the entire app to 1 cpu by setting the process affinity as already mentioned.

I believe the 2 CPUs get out of sync in their timing. Its been widely reported that the longer the computer is on, the worse the problem is.
 
happens on my laptop, it's fun to play CS and CS:S that fast! It sure is a challenge for NFS:U though, haha

No. This kind of advice is horrible. You need to identify the problem. Or you will likely encounter it again. This is also alot of work to go through for a small problem.
 
I have the Intel Pentium D 830 3.0ghz and its by far the biggest pos ever. its just that they havn't developed the correct chipset for it and not many programs support "dual core" technology, hence me going witht he AMD X2 since amd makes an actual driver so stuff supports it.
 
GTA:SA is know for this issue either down clock your cpu or get a speed limiter, cant recall whereor how u can but i know some people have had mention of it.

Yeah that is why the one of the first guys to post said he had the same problem on his X2....Man some people are stupid....

woah. that's funny. guess you didn't notice the x2 comment(s) did you?


and...intel makes probably some of the finest chipsets on the market. just fyi.

Lets change "finest" to "most stable". If your looking for rock-hard stability in the Intel lineup, then the Intel chipsets over VIA or now nVidia is definetly true... They're always the easiest to get going.
 
Do you have a video of this occuring? I would say demo the CS, but CS demo's operate off the system you are playing on, so if you arent hacking im never gunna see the problem.

Can you force the game to run on one core? Or possibly set it up to run certain programs executed on only one core?

I remember GTA3 having a framerate limiter option you could turn on or off from the Options menu. No idea if San Adreas has that option however.

That wouldn't help ... all timing related calculations are affected. The game is making sure that the correct amount of time is taken into consideration for each frame (which requires timing code). With the limit, it puts an additional wait state in there to cap the framerate at 30fps (which requires more timing code).
 
To anwser a few questions...

I do not have a video of this occurence but I will try to produce one this weekend...
And...I can set affinity to CS and it fixes the problem, however GTA:SA does not allow this and gives an access denined error when I try to set the affinity.
 
If I recall correctly, there's a command line option that lets you "set" your CPU affinity while the program starts. I used to put it in shortcuts to certain games when I was running dual Athlon MP's.
 
I have the same problem with GTA:SA "running fast" and have been trying to find the exact reason. Yes, dual core AMD system here. Anyone got any links?
 
Hehe, I am well aware of processor affinity, I was looking for a link with documentation that PA is in fact the root of the issue I am seeing and others with the issue. Thanks for the link though, certainly interesting reading.
 
FYI, killing affinity to one CPU solved all my issues. :) Thanks for the insight guys!!!
