Quoting Teun-A-Roonius, reply 1You should probably invest in a processor with a lot of Ghz' on each core. It will help more than buying a new video card.
This. It's a single threaded game, CPU single core speed is king.
That said, what you want to play is going to lag no matter what hardware you throw at it if the game goes on long enough. The engine simply can't handle it anymore.
problem is that and the reason why multicore has come out to begin with, is we are very close to the theoretical core speed limit, hence why to get around that issue they released multicores to begin with.
A single core can only relay a single instruction at a time per unit of time. and the theoretical speed limit is C, meaning speed of light. the amount of heat being generated by these cores as they keep trying to make them faster and faster is a product of the sheer thermodynamic effect on channeling more and more power through them.
eventually you will reach a point where no matter how much cooling you have, how much power you have, the processor will not go any faster.
So the companies decided if you can make one core go faster, then just have more of them. since directing 4 instructions at once through 4 cores is actually better and more efficient then making a processor 4 times faster.
So now the current thinking is create nanometer processes that are smaller and smaller to fit more cores on the same die. thus indirectly yielding a faster core.
How ever this doesn't help SINS because it doesnt take advantage of multicores to begin with. If it did It would be WAAAAY faster and less laggy then it is now.
My hope is that SINS 2 takes advantage of this.
