I don't understand why you guys are bashing him. He is actually presenting quite a good advice. Almost all new games released nowadays dry hump your GPU so hard that the friction causes a heart attack in the overall rig. Optimization and availability of a wide array of graphics settings are so vital, yet few developers pay attention to that.
It is most likely because what Golem is requesting is so obvious: Everyone wants the game to be optimized.
Optimization is somewhat of a meaningless "plus word".
It would probably be more productive to discuss what hardware the game should be optimized for.
Because the more time the devs use on optimizing the game for old hardware the less time the will have for other parts of the game.
I don't want a game where the fact that some people have 6+ year old computers bottlenecks it in a big way.
This is not only limited to GPUs. For instance if we want the game to able to handle 250 people in one server and one map along with a lot of NPCs we are going to need a lot of computation power (CPU) and maybe a decent chuck of memory to store all of this data.
From the very little I know about game design: it takes a lot of resources to optimize a game. Which is why even big companies slack in this regard.
Though I could run the alphabeta on my old rig which was from 2009 (except for the GPU which was from 2011 or so) without any problems.
And the alphabeta was according to the devs not optimized at all (or very much). So I don't think you have much to fear at the moment.
