January 8Jan 8 I have a 5090, always run 4k DLSS on lg oled C4, very happy with this, but which preset should I use? My testing shows to me preset K, but that does not make any sense when new presets are out.

January 9Jan 9 Think I'll wait until some further tuning is done on this before subjecting my ageing 3090 to 4.5. TBH, 4 with preset K and framegen is already pretty much perfect in pancake mode so not feeling like I'm missing out on too much more. On a side note, I started a new playthrough of Cyberpunk for the first time in 4 / preset K, and whoa, that game looks stunning now and runs like a dream. Path tracing / ray reconstruction at a steady 80FPS with a 5-yr old rig?

But as I said earlier, peoples milage can vary, and I myself admit to still being a bit fuzzy on all the parameters. Hopefully this is useful for some. We are all connected.....

January 9Jan 9 In VR it is a godsend - 4080s, quest1, preset L, quality: looks like TAA with oversampling but buttery smooth performance and no aliasing at all, the displays ghost a bit but they're much, much better than before with any DLSS setting. Tried PMDG777 and fenix and all went very very well. Edited January 9Jan 9 by dzmitry

January 9Jan 9 I am in VR (Varjo Aero) and the new DLSS 4.5 with preset L nearly completely eliminates ghosting of the speed and altitude tape of an airliner PFD as compared to DLSS 4.0 with preset K. That's with NV driver 591.74, RTX4090, 13000K, and using DLSS in-game "BALANCED". I think it is a big step forward. DLSS has the advantage that it eliminates the shimmering seen with TAA and it adds important fps (in my case 10-15fps) to the game which is extremely important in the demanding VR mode. Drawback until 4.5 has been the ghosting seen in glass cockpits, which are now gone with DLSS 4.5 or at least can be easily tolerated (the N1/N2 indications still show some ghosting on the engine display).

January 9Jan 9 I have read elsewhere that selecting DLSS instead of TAA uses more VRAM. Is this correct? Christopher Low AMD Ryzen 7 9800X3D CPU / 64GB DDR5-6000 RAM / 12GB Nvidia RTX 4070 Super GPU / Gigabyte X870E Aorus Elite Wifi 7 / 1+2TB Samsung Evo Plus M2 Nvme UK2000 Beta Tester
January 9Jan 9 I tried DLSS 4.5 with the 591.74 driver. There are improvements there, but none that I really need for my VR flying. In fact I got somewhat lower FPS so I reverted back to 580.88 and DLSS 4 and got the FPS back. Every driver I've tried since 580.88 has been like this with my computer, see my sig. Hoping that it'd be different this time, oh well. Now back to sim flying.

January 9Jan 9 Has anybody already tried it in 1080p, with a locked native framerate (let's say, 30 FPS)? I understand the ghosting effect is worse in these conditions I mention. I can test, but not until next week. This weekend I'll be a bit busy for personal reasons.

January 9Jan 9 I have been using DLAA for a long time, though have tried DLSS quality using Profiles K, L and M. For DLSS quality, I found profile M to be the best. Is there anything here at all if you use DLAA? For me, it seems that I have lost a fair bit of performance in DLAA since installing the new Nvidia driver and DLSS 4.5.

Preset M is power hungry. extra AI costs 5 x more compute, i.e. extra GPU cycles = more workload, as explained by Daniel Owens youtube review of DLSS 4.5 that I had posted above. you can always use the older, less demanding preset K.

January 10Jan 10 I found that the new DLSS 4.5 with preset M did not work well using Smooth Motion instead of FG. But it works great, really great, with DLSS frame gen. DLSS 4.5 improves performance a lot for me. 4.5 + M and DLSS Anti Aliasing yields less glass screen blur than the old 4.0 with same settings. But It still can't match TAA.

January 10Jan 10 messed around with new DLSS latest version tried in PMDG 738 at FNC, then Fenix A320 at LHR. FPS wise its the same before updating just ignore it on the differences I get the same regardless. Pulling 100fps at LHR. Default preset.
