How to Force useing Multi-core

[OSBK]

i don't know if it's thr right place but i'll post my topic here. as everyone know if you have 2 cpus one is 4.6GHz per core and the other one is 3.0GHz the first one would be better for gaming even if it's just quad core cpu. so what i'm asking, is there a way to force games to use all of cpu cores. i do have a 5930k it had 6 cores but a bit low frequency. anyone who can help me with this. i tried task manager and i set how much cpu cores to use but it doesn't make any diffrent ?

If a game is not programmed in a way that uses all the cores, then it won't. It's part of the structure of the program. You can't make the original Homeworld game from 1999 or Deus Ex utilize more than one core. It just won't do it.

 

Even if you could, there would be no performance benefit, because the programs were made in a way that takes advantage of a certain amount of resources. It'd be like having eleven people come to carry a piece of plywood that could easily be carried by four. At some point the benefit diminishes.

CPU core utilization is entirely dependant on game developer support. You cannot force a game to run on more cores than it is designed to.

Well you could but you'd have to mod the game extensively, which is way to much work

It would be so cool if this was possible. My games would be so much faster, but it is entirely up to the game developer.

Some games are designed to utilize as many threads as are available, but that's a very rare thing these days - we'll have to wait for it to become the norm. Most take advantage of four threads.

modding every single game is gonna take forever, isn't there something that works for all games

i think that DX12 have this feature. but what about other systems

Using up all the cores all depends on the game you are playing...

Nope, sorry unless they use the same engine and you mod that your out of luck

it's Crysis 3, it's a demanding game but it only use 2 threads and the other 10 threads are idle

what is your fps?

 

so its only using 2 cores?

It's not that it's too much work, it's usually not even possible. I'm no expert on programming, but I think this sort of thing is written deep in the source code, and most publishers are never going to let you see that.

 

Besides, if you're someone who could do this, you probably have a career. You probably aren't spending your time re-writing public domain games for eight-core support.

Since the first multi cores CPUs where produced a lot of engineers, software developers, researchers and others have been looking for to multithread a programm automaticly.

Despite to several milloins spent in research and >200 prigramming languages we have nowadays, there is no sigle one that can do this in an efficient way by it's own.

Multithreaded applications still rely heavily on the skill of the developper to achive a decent speed up.

what is your fps?

 

so its only using 2 cores?

i'm playing it at 1440p maxed out, and i get about 100~130 fps, and it only use 2 cores 100% and the other are idle . but when i go up to 4k the performance get down to 55fps, with some overclocking for the both GPUs and cpu i get extra 10fps. but it still using only 2cores

It's never impossible, but you would have to rewrite the base code for some games, which would mean rewriting most of the game (which yes isn't worth your time at all), now getting something akin to the source code isn't that hard but requires special tools for most games, and once again isn't worth your time as you implied.

 

In short it's possible but a huge waste of time.

i'm not a powerfull developer, it's far away from my abilities. rewriting a whole game is like making a new one, and as "typographie" said you probably have a career if you can do such things. but let's not go that far, what about DX12 and the enhancement of multi-threads tasking ? is it a thing cause i didn't fully test windows 10

-snip-

the easiest solution is to overclock your cpu, the 5930k can easily reach 4.0-4.4 ghz without pushing much voltage on it and with a decent cpu cooler.

Dx12 will only apply to new releases, if you were to try and make an old game compatible with dx12 you would have to rewrite it, also dx12 really only makes it easier for a game to support more than 4 threads, as dx11 already allowed for quad core support

and until now there is only a few games that support dx12, and i don't think crysis 3 is one of them. looks like overlocking is the only solution, but it still not enough, i'll keep searching for some tricks i might find something helpfull, anyway. thanks for the assist guys.

Very few games use more than one or two cores. Easiest way to see what games would really benefit from more cores is to search for wikipedia what games use Direct X 12.

You can in some Steam games but yeah that is 50/50...

 

Set Launch Option: (paste the one you have there and do not forget the -)

-threads 4

-threads 6

-threads 8

-threads what ever your count is?

i didn't know that, i'll try it soon. and it's 12 threads (6 cores)
