This shooter doesn’t differ much from Doom 3 , except that its plot has nothing to do with dark mysticism. By the way, Quake 4 is developed by Raven Software in collaboration with id Software. The game carries on the famous Quake series and puts the player again amidst the war between the human race and the Strogg civilization. The gameplay is quite engaging with some tactical elements – you get a small troop of marines under your command once in a while. The missions vary in character, and there is also some battle machinery you can control. The levels of Quake 4 are bigger than those of Doom 3 and are better illuminated, but you can still spot some similarity between the two games. The engine seems to put restrictions on the size of a level. The textures are not as detailed as in Half-Life 2 , but the interiors and characters look nice anyway. Friends and enemies alike are detailed but lack polygons and, like in Doom 3 , people still don’t have a tongue in their mouths – this spoils the overall impression somewhat.
Although this is an OpenGL application, the results are different from what we’ve seen in the two previous cases. The ATI RADEON X1800 XT has a very good speed here, being just a little slower than the GeForce 7800 GTX in the “pure speed” mode. It is possible the game requires a large amount of graphics memory, and the RADEON X1800 XT is the only graphics card participating in this test session to carry 512 megabytes of GDDR3 SDRAM on board.
The ASUS Extreme N7800GT outperforms the RADEON X1800 XL in high resolutions of the “pure speed” mode, but falls behind it as we switch to the “eye candy” settings. It’s strange, but it’s a fact: products from ATI Technologies, RADEON X1800 XT and X1800 XL, manage to beat their rivals, GeForce 7800 GTX and 7800 GT, in a game that uses the Doom 3 engine!
Overclocking doesn’t help the ASUS Extreme N7800GT much, providing a speed gain of 15% at best. This is enough to get even with the RADEON, though.
The SLI configuration with two Extreme N7800GT cards has the best result, but note that it’s not so much better than the single RADEON X1800 XT. Moreover, the performance of the SLI system is sometimes a little lower than that of the ATI RADEON X1800 XT. This fact agrees with our supposition that the game requires a large amount of graphics memory to run.
