OK home at last!!!!
Here's what I'm working with: GA-EP45-UD3P Motherboard over clocked FSB to 400MHz,
CPU is a E8500 over clocked to 3.8MHz, 4GB of Gskill DDR2 RAM running 5-5-5-15 at 1066MHz, EVGA GTX560Ti running at 900MHz with 1GB of DDR5 RAM. All powered by a Corsair HX1050 (over kill I know, but I have big planes....lol). The OS is win7 Ultimate 64bit. Clean install done maybe 6 months ago.
Now as far as in game settings: Video Resolution is 1680x1050 Texture's are set to 2048 and Anti-Aliasing is maxed out. As far as the sliders in game they are all on max and all the boxes are checked with the exception of the building shadows, shadow textures are at 2048 as well.
What I have done to remedy this is unchecked the boxes that have to do with shadows and I still run into the small lag when rendering the ground with others close by.
As far as what my settings were when I had the GTX9800 (nothing at this time was over clocked, and my PSU was a 550watt rosewill) I did have any of the shadow box's checked and was running 1680x1050 with textures at 1024 and Anti-Aliasing was maybe half way up the slider or more, cant quite remember that. but the thing is I rarely had any issues with rendering the ground in heavily occupied areas with this set up..... I'm starting to think I was hoping that my new video card would be the mother of all eyecandy bringers.
Here's what I'm going to do now, right after I post this..... I'm gonna bump my textures down to 1024 and my Anti-Aliasing down one notch and see what happens....
Again thanks to all who have taken the time to help me beat this dead horse even deader!!! LOL
