I watched a video with compatibility analysed and generally it was very good and much better than expected on the release day of the console but I understand the chipset does date back to 2020 so I guess they had plenty of time to get the code in a decent shape but still much better than expected. It seems like the Switch 2 CPU's are mainly running code directly like some of the best emulators with systems with ARM processors but the graphics are more difficult. The reason I say that is games that had inconsistent frame rates on the original Switch are now running at much more consistent frame rates overall but surprisingly the resolutions stay the same even to the point where games that dynamically scale with the load were showing the same traits as the original Switch. I realise Nintendo want to sell upgrade packs so this could be a commercial choice but I was still expecting the dynamic scaling to be more forgiving on Switch 2. I suppose it could well be the Switch 2 has some sort of interpretative layer for games without upgrade packs and it shows the Nvidia chipset is fairly different this time around.
I'm also curious about the graphics hardware between the two systems because the original Switch supports high performance but lower precision FP16 graphics so its 388 gflops at fp32 is actually doubled to just under 800 Gflops for fp16 precision same as PS4 Pro gflops doubling at fp16 but the Switch 2 doesn't have that doubling for fp16 and some Switch games are written and optimised for fp16 calculations. I wonder how they will be effected. A modded Mariko Switch overclocked can do about 1.2 Teraflops at fpt16 i.e. a 50% GPU speed boost and then a doubling of gflops due to fp16. I don't have a modded Switch myself but I believe on those you get higher frame rates but also dynamic scaling is reduced with regard lower resolutions. I just wonder if there is a floor on Switch 1 GPU emulation on Switch 2 and to get better emulation with higher resolutions you have to rewrite the code to optimise it for the T239.
Overall I have to say I'm super impressed with the reports of the Switch 2 and its functionality out of the gate but I still think it will be a hard sell for a lot of people at current prices.
