Lag starts once city is developed

[Adnan88 0]

Once I develop my city at a good rate, with lots of bats and stuff my game starts to lag every time I load that city....I selected that the computer runs the game on one processor....I think im gonna change it to two again...these are my specs:

Inter Core 2 Duo CPU P 8700  @ 2.53Ghz

4.00 GB Ram

640 Bit OS Windows 7

What you're seeing is normal.. as has been pointed out in other threads, the game is coded as a single thread and the scheduler is internal, not turned over to the hardware.. consequently it doesn't matter what you do with your "processor limitations" it will still run in only one thread.. in some cases (depending on how your hardware works) it won't run at all (or at least has major glitches) if you run all (both) processors. I will say however that I've never seen people with Core2Duo processors having a problem, so I imagine it will be unchanged in your case.. its likely your affinity change is superflous anyways. However on especially early AMD Athlon X64 units, it needs the dual core optimizer supplied by AMD.

Your lag will remain and grow worse as you expand your city sizes and as you add custom content.

Setting your processor affinity to one core will set you computer back to the turn of the century.  The advantage of dual core is that it basically doubles the speed of the computer.
