I can understand wht Mr love is saying.
FPSC does not have the sharpest or best visual texture representation around on screen, but thats to be expected.
There are many reasons that contribute to this as well as those pointed out.
In fact textures should blur somewhat at distance as thats how humans see things in reality and it adds to the feel of perspective. Eagles can see detail at great distances - humans cant , not that you have great distances in FPSC but enough to need a feel of perspective.
Of course in FPSC as in many engines, blurring can occur also if you are very close to an object and turn to observe the texture of say a wall that you are right up against. Thats typical of most games.
These instances of blurring are also a factor of game engine camera settings - and I prseume that FPSC has some specified in source. Nothing unusual there.
FPSC overall is reasonable in this area.
However you should not expect an end user to have to adjust any setting external to your game programme and if adjustments are possible then they should be adjustable as with most visual things from menus within the game. e.g. ambient lighting, screen resolution.
I am not saying one should expect a prog of the status of FPSC to have such user controls built in, but neither will game players expect to have to play around with their video card settings or anything else external to the game to make adjustments.
You can say its easy - but very few game users in reality will be prepared to do it. They will just get on with it and play the game and adjudge the quality of graphics and your game by and large by the defaults the game designer has supplied.
In other words they may moan about it but will do nothing to change anything - thats they way the mass of humans are in general and that includes many of the of end users FPSC games will be aimed at.
