SearingYou can do good reflections ala Gears 5. We need better looking hair and trees and textures and so much more than lighting imo. I'd like a 32GB VRAM card instead of an RT card. There is so much wasted silicon with the latest cards.

bugAnd that's what RT will eventually enable: when you get reflections, ambient occlusion for free, you'll have more HP at your disposal to throw at geometry. But not just yet when games are still mostly about rasterizing with a little RT on top.

I'm not even sure why we're discussing this, it's not like RT is a gimmick Nvidia pulled out of their hat yesterday. RT has been the choice for professional rendering for decades. Because it produces superior results.

Searingit produces inferior results, we are playing in real time, not offline... ugh... anyways the RT believers are not worth arguing with

xkm1948Based on TPU review of Control. RTX on will cut 2080Ti performance to half in 1080p

www.techpowerup.com/review/control-benchmark-test-performance-nvidia-rtx/4.html

Without DLSS, 2080Ti gets about 100FPS avg at 1080p, 50fps avg at RTX 1080P.

So now RTX3090 gets about 100 fps on RTX 1080p (>2X from this chart)

That means RTX3090 needs at least 200FPS on regulation 1080p, that is without RTX. Of course this is assuming no RT efficiency improvement. Let's assume there is some major RT effieceny improvement so instead of 0.5X performance penalty we have 0.7X performance penalty. Then RTX3090 would be running 133FPS to 150FPS without RTX. So a 30% to 50% performance uplift in non-RTX games. Also we have 5248 versus 4352 CUDA core. So CUDA core increase by itself should give at least 20% performance in nonRTX

That is just some quick napkin math. I am more leaning towards 30%~35% performance increase. But there is a good chance that I am wrong
