It’s no secret that Hammer effectively makes a computer unusable during a map compile. I know there are 3rd party compilers to get around this, but I thought I would share a different method that keeps my computer from freezing (or even lagging) during a native compile from within Hammer:
You can use this application to limit the compiler to use only a certain amount of cores on your CPU, so that your computer will not freeze. It’s pretty much a set up once and forget about it process:
^Process Watchdog effectively limits the CPU usage to 75% when compiling, and only adds on 30 seconds to a regularly 8 minute compile time. You can have Process Lasso run in the background when the computer starts, so that you can completely forget about it once you’ve applied your settings.
Just thought I would share this with any fellow mappers who are interested! It is a paid application (if you’re honest and don’t look for it elsewhere). Well worth the money for how often I compile maps, plus it has a lot of other useful features.
