I read the previous posts on reducing lag, but i don't dare fiddle with delta time or any other settings in case i make a horrid messup. But my pc seems to have quite the issue playing b27. As far as i know cc is most dependent on processors and ram. But my old single core 512mb xp machine could run it quite nicely *it's dead now* But my dual core 4gb ram machine is having nasty lag issues. I wanted to turn off timescaling as that according to some can help, but i tried (Ctrl + O) but it didn't turn it off. I am running on the lowest in game resolution. Any tips that could boost performance? And yes, all my drives are up to date. Updated them today just before this post.

Don't be afraid to fiddle with the settings, if you really mess it up bad you can delete Base.rte/Settings.ini and when you reload the game it will be restored.

I messes with the delta time a lil bit. Tiny bit better but still getting some nasty lag when it comes to some unitec activities in skirmish like the zombies one. I turned off the timescale slowdown in the settings by changing the time to 0. And i've shut off all un-needed processes whilst im playing such as my graphics tab drivers. Does anyone else get horrific lag like this with an ok pc? As i was pretty sure a dual core with 4gb ram would have been perfect for this on medium res's with no lag.

Check the console (press ~ on a US keyboard or ` in most other places) and see if there are a lot of messages getting printed there.
