Yes but the argument here is that people think you HAVE too. As a programmer i can tell you out of experience that programming can make or break how the game runs even crysis could probably run smoother if they had a smarter programmer. The problem is everyone just assumes Good graphics=monster pc needed=most can't run it. You can have good graphics without a super computer its all about the programming its isn't a law of nature that can't be changed people need to stop just assuming these things.
And im not sure you really remember what a big acomplishment those graphics were in 2007. Back then this was ground breaking stuff.
I'm also a programmer, and I see where you are coming from. I remember playing the demo when they first released it and being blown away. The sequel, Crysis Warhead, apparently included sizeable improvements to the graphics engine's efficiency. However, the arguement that a game can't look good without a monster pc is not one I was trying to make. While its true that having a better pc can let you crank the settings to max, games like Half-Life 2 look good even on the lower settings. I personally feel Sins did a good job with the graphics.
The big issue is that unlike a FPS, in an RTS you have to take a different approach to making the game look good. You cant just hire an art team to go and spend a year and a half creating jaw-dropping textures for everything in game. Why? Doing so, especially with a small studio, would cost far too much for the results. Face it: most RTS genre games are played from a zoomed out perspective. So instead, you have to focus on making things look good on a wide variety of machines while zoomed out, which Sins did. This comes at the cost of bleeding edge graphics, because you have to accept that you're focusing on the big picture in a game like Sins, instead of the little one.
So if you're complaining because stuff doesnt look good when zoomed in, that's the reality of the situation. Spending a huge part of your art departments time working on close up textures and graphics optimizations isnt an efficient use of time. On the other hand, if you're complaining about how the graphics dont look astonishing when zoomed out, that's a different issue. Some of that can be addressed with mods, and the devs have updated the high end textures, but comparing the value added from the microexpansions and the patch rebalances, spending money completely overhauling the graphics is a waste of time, which as a programmer you can probably understand. That said, it would help if you posted some ideas or suggestions. Simply asking if the devs are going to redo more textures or add more special effects doesnt really help (though if you want more special effects, check out some of the starbase abilities in entrenchment).
