Setting program affinity in Win10

I've heard of ways to make certain programs use only one core by going on the process tab in the task manager and setting affinity, but I've never found this affinity option. 

I have installed a very old game and it lags because the PC isn't rly built for that, and I need some help to figure out how to do this.

Answer

Using Compatibility with Win95 or 98 (XP\7 won't help) should force the game to run on a single core .

Failing that, if you are able to Alt\TAB out of the game and back in successfully go to Task Manager>Details tab and

R\click on the Games title>Set Affinity and select cpu 0 .

Still not go ? You may want to enquirer with GOG support about running DOS based games on cpu's with more than four cores.

(I haven't had any issues with the few DOS based games I have when using a quad core cpu. )

It may also be possible to use a batch file to launch the game with a single core, but I wouldn't know how to set it up.

What game, btw ?
