LOADING TIMES: if you have slow loads, read this
Our loading times are actually very good, and our reloads are extremely fast. If you find this is not the case, I have bad news for you: your system does not have enough RAM. If you lower the texture detail settings from VERY HIGH to HIGH, you will see your loading times get much, much better.
You may say "but I have a 64MB card and 256MB system RAM!", that should be fine for a lot of the levels, but when you're using the HIGHEST level of texture detail, you're going to need more than that on some levels. If you have 512MB of system RAM, you should be fine with full-on cranked-up detail levels.
