After reading hundreds of posts, and seeing actual FPS of 20 to 30 FPS over land and buildings in low setting with average PCs reported by many players , I have to admit that if Luthier reaches his goals , we are in for a good ride within few weeks:

1. Performance increase. Over terrain, the two things that slow things down the most are trees and buildings. We are currently in final stages of testing optimized buildings that almost double the FPS over London on a test machine.
Tree optimization is a little farther away. You will probably see changes in how trees are rendered, they’ll take longer to appear over terrain, but once again, performance increase should be significant.
If everything tests correctly over the weekend, both of these should be released by early to mid next week.

2. Enhanced multicore support. The mode that we unfortunately were not able to finish in time is sending all render to a dedicated CPU core. The mode is working but somewhat buggy. It easily doubles the FPS, and the performance boost is especially noticeable in larger missions with lots of stuff going on.

So double + double should look good ! And add the SLI in the near future And maybe 64 bits...

Salute !
