Haven't been here for long since last time ^^"
Recently, I got back to this game and started a new round of scenerio.
I've been suffering from system lagging everytime I play on my homemade map.
Now my system started to lag again, no matter I adjust the system.
(Every time the lagging happens, the FPS rate drops about 20 to 40.
Usually, when I view the whole map, the FPS rate is around 100~120,
and when I take a close view to trains and buildings, the FPS rate is about 50~80 initially.
These rate drops while the game proceeds and the scale of cities grows)
So is anyone have such experience and knowing how to fix the lagging problem?
Here's my system detail--
< Hardware spec >
ASUS F3SV (notebook)
CPU: Intel Centrino Core 2 Duo T7300 2GHz
RAM: 2GB
Graphic Card: nVIDIA GeForce 8600M GS
CPU temperature normal/during gameplay: 53~55 /60~63 (centigrade)
GPU temperature normal/during gameplay: 73~75 /91~96 (centigrade)
< In-game setting >
Model detail:
-Building: 5
-Train: 8
-Trees: 3
-Ground: 17*
*if under 16, the edge of coastline will suffer from severe "zigzag" problem after save & load, so I have to use this grade
Draw distance:
Buildings & trees: 4
Trees: 4
Trains: 4
Tree density: 40%
Distant fogging: OFF
Texture detail: NORMAL
Mipmapping: Tri-linear filtering
Enable +0.5 mipmapping bias: OFF
Enable anisotropic filter: OFF
Draw clouds: ON
Draw ground detail texture: ON
Particles: NORMAL
Shadows: DEFAULT QUALITY
Font shadows: ON
Ocean waves: ON
Water reflections: ON
Anti alias: OFF
Use safer refresh rate: ON
< Map detail >
Map size: 640*640
Total cities: 147**
Current connected cities: 61
Current trains : 41
** I used to have over 280 cities
![Shocked :shock:](./images/smilies/icon_eek.gif)
So I have no choice but to greatly reduce the number of cities.
When I connect around 50 cities and have more than 30 trains, the system begins to lag,
and getting worse when I purchase more trains or extend my network.
Also, the loading time and the time I end the game grows with these factors.
If anyone knows where the problems are, please let me know!
(In fact, I really don't want to create a smaller map.
After all, this current homemade map took me lots of time to finish and debug...)
