Performance in Strategy Games
Age of Empires 3
Age of Empires 3 using a lot of SM3.0/HDR special effects, graphics cards with more pixel processors, i.e. based on ATI’s Radeon X1900 processor (R580), have the best results in this test. The Gigabyte Radeon X1900 XTX beats the Gigabyte GeForce 7900 GTX in high resolutions as you can see. The Radeon looks preferable, yet the other card is also sufficient for playing this strategy in any resolution with enabled full-screen antialiasing.
Warhammer 40.000: Dawn of War
It’s different in Dawn of War: the Gigabyte Radeon X1900 XTX has a min speed of less than 25fps even in 1024x768 whereas the Gigabyte GeForce 7900 GTX easily yields over 35fps in a higher resolution. Why? Because the game makes use of stencil shadows the Radeon X1900 lacks any means to accelerate the rendering of. When there are many units in the screen, each casting such a shadow, the GeForce 7900 with its UltraShadow II technology is obviously better than its rival.
