i didn't know people had overloaded CPU to be honest, mine doesn't go about 25% when in space i get 10%
GPU on the other hand is battered, my poor 2080ti is certainly working its little heart out when on foot or in stations in a ship
If you uncap frame rates and aren't seeing GPU load in the upper-90% range, there is a bottleneck somewhere else. It can be CPU proper, or it can be the CPU waiting on memory. Even if it is the CPU, it's only takes a single logical core maxing out intermittently to be capping frame rate.
DLSS 3 can "only" create synthetic frames, similar to asynchronous spacewarp and motion smooting in VR APIs. So yes, it can multiply the displayed frame rate, but the part of the rendering done by the CPU is unaffected. I.e. if your CPU only manages to prepare only 30 Fps for your GPU, DLSS can help to double that (by inserting artificial frames), but scripts, animations, player input and so on is being processed at 33,33ms (30 Fps).
Yes. You are still technically getting the frame rate multiplied without there needing to be more draw calls or engine overhead, but latency isn't improving.
DLSS 3 implies the upscaling and asset replacement already part of DLSS 2; there is probably a way to use it without upscaling, but that would be a very niche use a DLSS2 upscaling probably has fewer trade offs, so most would only want DLSS 3 if DLSS 2 didn't cut it by itself. It also mandates NVIDIA Reflex to mask some latency that would otherwise be more problematic.
..the issue with DLSS3, in my opinion, is that it will require a 4000 series card, and I don't like the prices - nor the marketing strategy as it is today.
Same issue as earlier versions of DLSS. It's a proprietary solution that presumably leverages hardware only available on the GPU's supported by it. More likely this is not a hard limit (though frame interpolation is probably
much costlier in performance terms than upscaling and selective asset replacement, probably prohibitively so on earlier hardware), but a marketing value-add.
Wouldn't buy a part specifically for it, but if I were on the fence, it might push me over.
