Electricity price rises
« on: Fri, 27 May 2022 10:57 »
With my electric tariff going up by 70% I think i need to make drastic changes to my 747 simulator. I have 5 Intel NUCs running PSX and a PC (with a 3090) running MSFS 2020.

I've worked out it's actually cheaper running AWS EC2 spot instances then running all the NUCs during a flight. So I was thinking replacing the NUCs with Pi 4 connected to the monitors and USB hardware. Then using a form of remote desktop to pass that through to the cloud.

I suspect that could be a bit laggy though?

Do you have a plug-in power meter? Something like this?

You could check if it makes any significant difference when you run your PSX instances at 48 fps instead of 72 fps -- except for the one PSX instance which is the boost server for your scenery generator. But if your scenery computer runs at a frame rate below 50 fps, you could set the PSX boost instance to 48 as well.

If you're lucky it might reduce the power by up to 20%.

If it's just about EFIS/EICAS screens, 48 fps is absolutely OK. The real 744 screens are updated at 50 Hz only.

The amount of extra points of failure and nuisance that you will introduce is significant. Consider that, too.

Thanks Hardy, yes I have a few of those. I've set the FPS to 48/2 and I'll see how that goes.

That was my worry as well Jeroen. I like to keep it as simple as possible.

Have you worked out how many kWh your setup uses?

I've got 2 PCs, 2 Mac minis, 7 monitors and various peripherals - they use a total of 0.44 kWh combined, which is less than I thought. At my current rate it costs me 13p per hour to run the sim.

According to my meter, the total for the whole sim is around 10 units/day. No idea what that means. My energy bill is 28.00 pence per kWh.
