Who made DLSS? Using ML to denoise ray tracing is massive.
- cubefox 3y agoI think DLSS doesn't do denoising. DLSS uses an ML algorithm to upscale frames using additional information like z buffer and motion vectors. Denoising is used to drastically reduce the number of required rays for ray tracing. I would guess denoising is done first, using a non-ML algorithm, and DLSS is done afterwards.
- nailer 3y agoDLSS does the denoising since DLSS 1.0 see the DLSS announcement https://www.youtube.com/live/4_g_Y0W1Xn8?feature=share https://www.youtube.com/live/4_g_Y0W1Xn8?feature=share (pardon the crappy gaming channel, it looks like Nvidia weren’t running their own YouTube the time) It adds frames since I think 3.0.
- cubefox 3y agoThat's odd, since you can use ray tracing without DLSS. I'm very sure it uses denoising even then.
- nailer 3y agoThere may be some confusion between upscaling and denoising. You might notice I keep editing my comment because it’s really really hard to find old Nvidia release announcements. Update: https://youtu.be/6O2B9BZiZjQ https://youtu.be/6O2B9BZiZjQ looks good around 3:54 Nvidia refer to “deep learning for image denoising” which to me seems like DLSS. Ray tracing without DLSS might be a different denoising technique. Is it really slow when you turn it on ?
