Did you not see the screenshots of this game and media that was distributed? If your system was not able to convey those images then it's your system
No it's not my system. I happen to have spec beyond that of the recommended requirements and am running the game at max settings AND the 8192x8192 tweak, WITH GPU Transcoding AND 16x AF. It plays at plenty high FPS even with those settings/tweaks, so it's not my spec. I can do all that on a mere GTS 250 1GB btw, so clearly the game was not made with advanced hardware and high end graphics in mind. Carmack himself was quoted as saying they were pushing for 60 FPS on any system, whereas Doom 4 will be made with higher detail and slated for 30 FPS.
Honestly I think a LOT of people here need a new eyeglass prescription because the one they're using is apparently outdated, like the graphics in this game. There have been numerous screenshots comparing this game's textures to 6-7 year old games like Doom 3 and FEAR 1, even an animated Gif on Nvidia's website posted here by AndyB from Nvidia showing the game with and without the 8k texture tweak. It's obvious in that demonstration Gif that even the highest detail pic shows textures nowhere near up to those of today's state of the art game graphics.
Play Just Cause 2 on just max texture detail even without everything else maxed and you will clearly see that common items like tires, barrels, walls, buildings, hell, most textures in the game for that matter, look FAR more detailed than most of the textures in Rage, and it's a game with a FAR bigger map and NO map loading to wait through. The real kicker is JC 2 has all that while taking up less than 5GB file space total for the entire game.
Rage has a lot of things going for it, but graphics, engine design (mainly the megatexture concept), and file size are not among them, unless all you care about in gtraphics is the art design and not the texture detail. To put it another way, why would Carmack himself have admitted he wished they'd pushed PC hardware further with this project, and why would id be coming out with an HD texture pack if the graphics were as great as some of you claim?
