Getting rid of Cache files-why ? How often?

[Blackdog_kt]

Clearing those folders forces the game to rebuild the shader cache. Back during the first few patches people would get graphics corruption issues after updating to a newer version if the cache files were not also up to date, so we made a habit of cleaning out the cache to force a rebuild/update as a precaution after each patch.

I think that at some point this has been integrated in the patching process and now the cash is automatically rebuilt after each update.
