multi-processor system

[hermanocabral]

is is true that if you have more processors (lets say, quad xeons), the games will run faster?

for what i know, games dont make usage of more then one processor...

 

[Dragoon42]

i think only a few games can use multi proc. Long run wise though, we'll probably be seeing more games that take advantage of it

 

[Aluvus]

Most current games will see no direct benefit from additional processors.

 

[hermanocabral]

does this make sense:

"games run using operational system resources.
with more processors, the operational system will run faster.
games will run faster."

Gaming wasn't faster at all on my dual Xeon... I'd rather have a single fast processor & a fast video card...

 

[hermanocabral]

i always thought that dual processor systems wasnt best for agmes at all, and like Fullmetal Chocobo said, its even better to have a faster proc. and better video card...


anyone knows why?

Know why what exactly? Why multi-processor systems are best for gaming? If that is your question, then the answer is that they are better suited for other more intensive tasks that are already taking advantage of multiple processors, such as rendering, animation, video processing, etc.

Most games just aren't multithreaded. Now games are being developed to use 2 threads simultaneously but anymore isn't really supported.

Why multi-processor systems are not better for gaming?

 

[w00t]

if the game is multi-threaded or takes advantage of multiple cores it could help

dual cores is good enough for gamers though and there is only a couple games that really support multi-cores.

dual cpu's and quad cpu's are overrated now we have the technology for multi-cores on one chip

single core
dual core
quad core

Because games really don't use 100% of a single processor. If they aren't coded to take advantage of two, it's piontless. It was nice gaming on one processor, and still crunching or rendering on another though. 🙂

 

[hermanocabral]

i just cant understand why multi processor systems are not better for games then single processor systems...

the logic thing would be that if you have more processors, your system runs faster and your games run faster....

 

[Spikesoldier]

for games:

if dual core cpu, = single cpu core speed, then take the dual core.

if single cpu > dual core cpu speed, then take the single core.

In my experience Quake 4 runs tremendously better with a dual core setup nearly 80% in my case. Oblivion showed maybe 20% but other than that I see little to no difference

 

[hermanocabral]

i know that two or more processors doesnt make difference (two or more processors is different of dual core processors).. i just wanna know why

 

[Baked]

You're using the multi-CPU so programs you're running in the background of the game doesn't slow down the game nor the system as whole. It eliminateds the bottleneck sometimes seen when playing online multi-player games. This also has to do w/ the GPU I"m sure. If I were still playing WoW, I could probably give you a better answer. I used to get lag and crash when we're doing some intense raid boss fights.

Well, Q4 specifically supports dual core. There's even an option in the game control panel for it to toggle on/off. Unfortunately, most games do not and until they do (via a patch), having dual cores is really not that beneficial if the game itself is not distributing the load over the two processors.

Ditto, I'm much rather have one really fast processor with a fast video card backing it up.

There is no difference. It doesn?t matter how the actual processing cores are implemented. Just as long as windows can utilise 1,2 or 4 (and so on)... cores. The only thing that differs with a single socket dual core, or a dual socket single core processor config is the I/O and memory subsystem.

what i want to say is that there is a difference between single socket dual core processor and dual socket single core processor...

i just wanna know why having 4 processors on one machine doesnt speed up games... the real reason, not just "because they dont use it"...

Most games currently are programmed with only one thread:

http://en.wikipedia.org/wiki/Thread_(computer_science)

Thus only use one cpu. If they are programmed with more than one, they will see a boost in performance, but at the moment, the video card tends to be the weak link in most people's systems, so the boost is nowhere close to 2x.

That is the real reason. You have to program the game to specifically take advantage of multiple CPUs(or cores) for it to use them. There's no magical way to automatically multithread programs at runtime, it has to be done at compile-time.
