Model previews super compressed and ugly

To add to it, observed that other's models have the same compression. I guess CGTrader just compressed previews market-wide to save some space. But it is too much...

That's interesting. I just checked it and found that it's only the first image that's being displayed with horrible compression artifacts, however if you advance to the next image, it shows just fine and if you get back to the first image, it will show fine too.

@ZB-Vision, that would make sense if compressed image would be replaced by high quality version as soon as it get chance to download, without any action from user side, but it's not the case. For me it looks like a bug rather than actual feature.

previews are ways to big in dependence of the physical resolution to load fluently and sharp right from the beginning when viewed. I´ve double checked it and have noticed that all previews are loading in realtime in the same time frame, so that when you view your 1st preview it´s simply pixelated a time long till all or most previews are loaded successfully.

To have a quicker preview of your images, without (really) a visible loss in quality for the naked eye, I use a tool that compresses all previews to almost 20% no matter if it´s png or jpg, and there is no difference in quality after that. Advantage, previews are popping up 5 x faster as natives and there´re no "artifacts" or any pixelation. Look here and test yourself: https://www.websiteplanet.com/webtools/imagecompressor/

Advice, of course don´t use it for textures!:-) just for preview images.

Right, forgot to check the creation date of the thread. Good that the issue was solved.
However what I´ve mentioned still applies till to day, but it´s a common issue within
the webdevelopment with preloading of multiple images in the same time.
