CPU Affinity, XP & the Patch

[andyfoot]

Is it just my imagination, or has the patch now taken advantage of the CPU affinity trick with XP. I checked by Alt Tabbing out of the game and found both CPU's had their affinity's set to on.

I seem to remember my Russian version of the game did, but the English DL version didn't. My game does seem to run smoother on my aging Dell XPS M1710 laptop, so well done to ED on another nice addition.

You won't get almost any boost in XP compared to Vista/W7.

DCS runs better in Vista, thats a fact.

Does this new patch really take advantage of multi-core processors??

 

One thing is set CPU affinity to all cores and another thing is to take advantage from all cores i think. Does this new patch really take advantage of four cores?? because i have noticed previously that setting manually the affinity for my 4 cores instead of improve the performance just lowered... looks like OS just switched processing from one core to the other, instead of doing multiprocessing.

This patch just sets affinity to all cores instead of just 1. Everything else is done by Windows (Vista better than XP). But DCS is not built for true multithreading (thou it has many threads executing I think), so going from 1 to 2 cores there's a huge boost (like 50%) but from 2 to more, very little improvement. I'm not soft engineer, but I think this is more or less what happens.

Difficult to tell, Distiler. I doubt it's that easy to tell 4 cores don't help, as multithreading and multiple CPU-usage are 2 completely different things. DCS may not support multithreading, but it definitely benefits from multiple CPUs if you use an OS that supports it.

As stated in numerous threads, running DCS on 2 cores on XP will only marginally increase your performance, forcing it to run on 4 causes more trouble than it helps.

 

andyfoot, your observation is right in a way. It looks like DCS runs more smoothly since the patch. But it runs even more smoothly on Vista/Win7 ;)

 

 

It doesn't matter how excellent a software is programmed. If the OS doesn't support a feature, it still can't use it.
