No, dark10x wrongfully criticized the precision of DC's color blending, which is always performed at full 32-bit accuracy unlike other consoles.
Forgive me, that's not what I was complaining about...
This dithering is going to be much more noticeable on a sharper VGA display than on an NTSC television, and that is what dark10x is complaining about...
THIS is the correct complaint. You're right, it generally looks better than some of the 16-bit output I've seen. However, I believe Voodoo 3 used a similar method to the DC (but really did only support 16-bit out). Is this right? Voodoo 3 has a much better 16-bit OUTPUT than the Dreamcast does. TNT1 is, I'll admit, worse than Dreamcast. The look is very similar, however, which is why I that was the example I used.
My entire complaint is that the resolution and output color depth is not high enough at this point. When using the superior VGA output capabilites of the Dreamcast on a higher quality display (such a PC monitor), flaws become more noticeable. It is not the fault of the DC's VGA output, however, it is simply that the games are not rendered in a high enough resolution for my liking and viewing them on an NTSC TV artificially masks some of the flaws. Some people, however, would rather deal with those while gaining the benefits of DC VGA. Based on comments various people provided previously when I showed various levels of filters being used on a PSX emulator, I found that many people prefer pixelated visuals to a blurrier look. I simply do not feel that way and believe that 640x480 is too pixelated on a decent sized VGA monitor. That's all.
Also, MDK2 does not do what I'm talking about. It's one of my favorite DC titles, and the corona effect in MDK2 is NOTHING like what I'm talking about. It does not function in the same way. MDK2's effects are similar to the original Unreal...
Also, the explosions look terrible in MDK2...
Come on man, I don't know all the details here. Can you not see what I'm talking about? Well, I have come to realization that you have very little "hands-on" experience. I'll try for another example...
Sunlight in ICO, for example, can filter through trees, around edges, and seriously change the tone of the screen. The depending on the position of the camera and the sun, the appearance of the scene changes quite a bit.
Other games go beyond that and have an even greater "bloom" like effect.
Also, what is the make and model of your monitor that you use for gaming? I'm just curious at this point to see what it is that you are using...
Ha ha, nevermind. Are you still using like an old CTX curved screen monitor or something (with cheap-o altec lansing speakers next to it) on top of some wooden desk?
