Question about multithreading and poorly optimized games

[MisterPotato]

Hey I was wondering if it is possible to have a program essentially run a poorly optimized game like GW2 for example

we all know how the game does note utilize CPU power very well since it uses very few threads. What if someone were

to make a program that runs the game and allows your 4 to x number of cores to all work at the same time like a splitter

Intel HD Graphics?

Intel HD Graphics?

Wait what

[Enderman]

that's what "reverse hyperthreading" will hypothetically do

use your cores combined for more power in less threads

this isnt something a program can do, it needs to be hardware programmed into the CPU

we should see reverse hyperthreading within the next few years from intel if rumours are correct

I'm skeptical of this happening, but if it does I wonder if it'll finally fix CPU bottlenecked games.

There was a hack for this in the game supreme commander forged alliance. But you really need to know how the engine works since multithreading is not something that can be done without a good robust design. If its not done correctly it can bring a program to it's knees through poor performance or crashing.

The only problem with this is how processing actually works and the nature of an individual process. Think of processes as really long, almost endless, equations. Stuff like "(2+4)/2", but much more complex. Thanks to order of operations, when presented with "(2+4)/2" the core must first solve 2+4 BEFORE it can divide the result by 2. If you try to distribute the same single threaded process across 2 cores, it doesn't really work because only one core can work on it at once. Each core acts as a separate brain and needs to have its tasks addressed individually by the way the code is written. For your idea to work, you would need to write a program that analyzes every line of code and identify how they all interract with one eachother, only then to literally rewrite the entire game from scratch so that it could be properly run on a multi-core processor. If you could somehow design such a magnificent piece of software, you would become a millionaire overnight. that piece of software would literally be the pinnacle of software engineering you you would be worshiped as a god among programmers. With all of that said, it for obvious reasons that it has not been done. Because it cannot be done.

 Thanks, you explained that quite well.
