Ah, infamous lead-free BGA problem. I have 3 8800 Ultra and none of them are working right now because of that problem. No problem with Quadro variants though, but they tend to run cooler and overclock less. Don't get me wrong here, nVidia did some very good engineering over the last 2 decades but …

Recent GeForce 2 GTS vs Kyro II comparison does not specify how much VRAM both cards have. Most likely it's 32mb (GTS) vs 64mb (Kyro II) showdown, where heavy tests just demonstrate VRAM bottleneck instead of pure performance difference between this cards.

If it was there, then wasn't, then was again Once again - you can't get dithering on Fermi, Kepler and Maxwell GPUs with fresh drivers. Period. So it seems like anything after G80 and before Pascal series just can't render 16-bit modes. Also you still get dithering on any card before G80 with …

Both Nvidia and AMD dropped 16-bit dithering completely. Most likely they even can't do 16-bit mode and just internally scale it to 32-bit.

Curious if V3 can match V4/5.. You can do some screenshots via HyperSnap for comparison. Otherwise the severity of banding Some color gradation is expected, due to low resolution of the sky layers and limitations of 32bit color. On the other hand, blocky bits are not expected with linear filtering.

While the renderer may have used uncompressed textures, when you saved the resultant-screen shot/frame-grab, you then saved the image in jpg and not at 100% quality, ergo it saved it in a lossy format (reduced quality for compression) and this is the banding issues seen in your images, not bad IQ …

This is the one you supplied, which looks horrible. I've posted only 1600x1200 screenshots on Q3DM5. Without texture compression. When did you create your screenshots and what driver and settings did you use? They were made around 2-3 years ago. You'll get the same result on any GeForce 1-7 and any …

I'd like to see what the actual texture image looks like. That would require software rendering, with linear texture filtering no less. VSA100 or modern GPU are pretty much as close as you can get to the reference. To my eyes these look nicer than the screenshots posted? Not really, blocky pattern …
