There is no replacement for displacement, uncompressed audio will always trump compressed audio, and native resolution will always look better than upscaled resolution.

DLSS is cool and all, but if they can't make a GPU that can run at native resolutions at high framerates, then I would prefer they spend more time with NVLink/SLI to make it happen.

Yeah, first world problems lol.

I mean, a turbo can compensate for a whole lot of displacement, and most people cannot tell a lossless file from a very high quality mp3 in A/B testing; decreased fuel and storage expenditure are obvious benefits with a virtually inexistent compromise in most cases. I don't think the comparison applies well here, considering DLSS isn't yet at a point where the increased performance accompanies an undiscernable image quality loss. Though, certainly, one hopes that will be the case in a not-so-distant future.

DLSS... maybe one day the performance/quality will be good, till then a good lanczos scaling is fine if they want to offer good scaling quality without killing performance.

I don't think DLSS is worse than Lanczos... It is probably better than Lanczos all things considered. Lanczos is a terrible option.

Telling me to render in 1440p and then upscale to 4K is the problem, it is not how you do it. I do not believe in any of these upscaling rendering techniques, they are all an unacceptable compromise to try to run effects that the GPU isn't fast enough to actually do. Geforce Experience will always enable DLSS for Control at 4K, even with the quality slider all the way up. So Nvidia thinks that settings with DLSS enabled can be considered "max quality" even on future hardware or two 2080 Tis (does Control support SLI?). They need to hear some pushback. DLSS and "max quality" are mutually exclusive concepts.

I am very worried about this marketing push for DLSS and similar technologies. I think that Nvidia believes this is an acceptable way to get ray tracing to run on hardware that is too slow. It is not. You do not improve graphics by rendering to a lower resolution and upscaling. We could have done this pretty well a long time ago, why wasn't anyone running Quake in 640x480 and upscaling that to 800x600? Because it looks like crap. They should put the development effort into figuring out better AA and optimizing ray tracing software and hardware instead. If you cannot make better hardware just turn down the settings, upscaling is not an acceptable way to get around poor hardware performance. That Nvidia, AMD, Microsoft, and Sony all seem to think that upscaling is an acceptable solution makes me worried for the future.

Remember the golden rule of statistics: A personal sample size of one is a sufficient basis upon which to draw universal conclusions.
Upload the computer to Dropbox and provide a link to it so others may download it to examine and give advice for repairs.

I don't think that's the point at all. I mean, I absolutely disagree with forcing DLSS on principle alone, but I think the main takeaway here is that RTX+DLSS is still better image quality than vanilla.

By "image quality", I mean how close to realistic the overall presentation is, not how well resolved individual lines are. I make this distinction because those are the main camps we usually see in this kind of discussion on OCN.

As for the "pushback" part, I agree. A suggestion to enable DLSS for increased performance when enabling RTX would be much more reasonable.

YES, THIS THIS THIS! Specially with the new killer 8K consoles coming Sometime soon would be a great time to start working on DX12 multi GPU. This won't make SLI users happy, but most of them have their head in the sand right now anyways. DX12 single card experience trumps anything you can do with 2x GPUs in forced DX11 right now. *glances over at 2nd 1080ti on the shelf...*

R.I.P. Zawarudo, may you OC angels' wings in heaven.
If something appears too good to be true, it probably is.
