graphic detail is set to default
1024 texture
The video card is
mobile intel(r) 4 series express chipset
The reason I have to use 1024-768 is that I use a 19inch external monitor and for full screen That is the only resolution that gives me the full display.
I have played with texture settings etc. but see no change in plane display.
Any suggestions ?
First off, like others are saying, your intel graphics are a BIG ISSUE... this is very subpar for gaming graphics. There are other laptops out there with many different BETTER graphics chips, and even some have a port in which you can upgrade the graphics, but from looking at your specifications, it appears that is not the case with your system.
The best you can do is keep your drivers up to date, set textures to 256 MAXIMUM (keep in mind textures are different than resolution), and if performance still isn't satisfactory, you can try turning your resolution down to 800X600 (you should be able to set it to 'stretch' in the video adapter's configuration page from control panel). Also make sure that all of the advanced graphics settings are unchecked from within aces high, except for bump-map terrain.
