Some old (and new) games consume 100% cpu. Look at Fallout 1 cpu usage. The game requirement is Intel Pentium 90 (!) Mhz CPU, but if you launch it consumes 100% cpu of any modern CPU (one core). It’s no good…
We found a global solution of this problem, called Battle Encoder Shirase (BES). It’s a freeware application, and can limit any application cpu (tested on win xp, 7,8).
Some of templates upgraded with bes support. If you define bes path (bes_dir global or local variable) job start bes before the app, and limiting it’s cpu resources. The limitation percentage is based on application, and your cpu calculation power. You can tune it with bes_cpulimit local variable.
You can found BES executer task example in fallout 1 template (task name: Bes cpu fix).
