Ads keep us online. Without them, we wouldn't exist. We don't have
paywalls or sell mods - we never will. But every month we have large bills
and running ads is our only way to cover them. Please consider unblocking us. Thank you from GameBanana <3
You have failed to optimize your map in any way at all, you can get away with this until your map becomes very large and very detailed, like yours. A fullbright map is better than an fps killing one. Read http://developer.valvesoftware.com/wiki/Optimization_(level_design) employing even the most straight forward and basic things will make a big difference.
