DX12 isn’t a magic bullet either. There still will be a mainThread to sync all the data to render a frame dx12 isn’t going to change that. Reading some performance benchmarks between dx11 and 12 shows it’s not always faster and can actually be much worse dependent on implementation and cpu/gpu used.
It reads like dx12 will help with low/mid tier cpus and AMD gpus mostly so yea, i do see it may help a little, but don’t expect a massive FPS jump or no more CPU limiting
I’ll be interested to see how the “balance of power”, between the CPU and GPU, is changed by the upcoming patch and also, once the VR patch has been applied, hopefully in October, whether that moves the bottleneck more towards the GPU??
I have a 2070 Super and MSFS leaves TONS of VRAM empty, leaving my CPU as the limiting factor accd to the devmode readouts. (9900k). I’m running triple 1080’s via Nvidia surround (5760x1080)
I guess a better move for me would be upgrading the CPU first.
I don’t think if you have a 20 series super that it’s worth the upgrade unless you have money burning a hole in your pocket.
I actually went to the effort to turn down the render scaling from 100 back to 80 (GTX1080 @ 4K) and was actually surprised to see a noticeable bump in frames. A320 at JFK was up from maybe 19-22FPS in the cockpit (Screens on) to about 28-34FPS? I then loaded up at a very foggy Queenstown (NZQN) in the Cockpit and saw 34-38 (then locked it at 30FPS and it didn’t drop under)
I couldn’t really see much difference between 100 Render Scaling and 80… so seeing these videos of people testing the 3080 at 200 Render Scaling on 4K… and having sluggish performance at 4K really isn’t surprising me. Drop it back to 100 and leave everything else scaled up to give a better idea of what we’ll really see.
Additionally, As a bit of a shameless plug (Maybe a little bit of shame felt) - Please, if you haven’t already done so and are considering an RTX 30 series… Please go and smash the vote button in the DX12 thread.
If we can get DX12 implemented, along with other efficiencies - I’m sure we’ll all start seeing performance in the Sim we can all be happy with. (The efficiencies can come either way but if we stay on DX11 forever, there’s little chance of Ray Tracing or Deep Learning Super Sampling (DLSS) further down the track)
@tgsweat10 It’s only something I’m just learning about now. I’ve read now in a couple of places that if you’re running your Sim at 4K - 80% should be fine… I dropped it and was quite happy to see it gave me a bit of a boost with no noticeable drawback.
