Now that i managed to get an RTX card we can finally test Minecraft RTX.
Minecraft RTX review
RTX gives Minecraft a whole new look. The caves and nights are so dark that you almost can’t see a thing. And when the sun is up you see a more colourful world with realistic shadows and water. You do have to lower the view distance take keep the game smooth but it is worth it. If you want to use RTX you need a RTX compatible texture pack like the one from Nvidia. Once you activated it you can enable Ray Tracing in the video settings. You do need an Nvidia RTX card to use Ray Tracing.

It looks so cool. Shame that you need an RTX card for it. I think they should have gone for the Super Duper Graphics Pack like they originally intended. That would be something all users could make use of.
