GPU load > 90 % during flight

Yeah, that makes sense, and is also sub-optimal. I guess brute force, and my impending 3090 purchase, may bring that down to 40%. :wink:

Or instead Asobo, redesign the interface, and only hammer the GPU if the user actually visits either the hangar or the globe map.

Perhaps one reason they didn’t is the load time prior to that, with the blue loading bar. We might get to the menu screen quickly without that, but as soon as you try and set up a flight, you would get another loading screen then instead.

It just seems like this could be made to work better. I’d like the option to ditch the 3D hanger view, replaced with a 2D thumbnail, for example. I find the hanger somewhat superfluous.

Do you have any FPS limiter in place? If not it’s a good reason to have menu using its full capacity and reach even 100%, as the game only do what you’re asking for. FPS limiter include Vsync (ingame or via graphic control panel), external program, etc. I don’t have any vsync or limiter in game. Just my NVidia control panel where I capped FS to 60fps. So game and menu never go upper than my monitor frequency and my graphic card don’t overheat for nothing. And I don’t have any tearing under 60fps, don’t know which magic they use here.

In other word it’s not the amount of work (with Hangar) which make the menu using more than 95%, it’s the fact it’s on free wheel

Hmm, I could look in to that.

But by the same logic, even the simplest 2D 8-bit retro side scroller running in full screen without a frame limiter should also run my GPU at 95%, and yet it doesn’t.

I think the real reason has already been highlighted. They are rendering the 3D hangar, with whizz-bang graphics, and the fancy globe view, even when you cannot see them. That is far more plausible.

Nope nope, sorry to say I’m right and just checked. I removed my 60fps limiter in NVidia Control Panel. The fps you see below are taken thanks to the GForce NV overlay:

During first loading : Capture d’écran (20)
During Main Menu : Capture d’écran (22)
During Hangar : Capture d’écran (23)
During Flight : Capture d’écran (24)

During all that time my GPU was nearly all the time at 100% and overheating 90+ degres !

This is because game was on free wheel like I said, rendering at it’s full CPU/GPU capacities without any limiter. A good way to heat my room and think I’m near a running plane engine with all my computer fans going crazy: :wink: I setup my limiter to 60fps right after this test, don’t want to kill my old good machine :stuck_out_tongue_winking_eye:

So you believe if I set my frame rate limit in the Nvidia driver to something really low, like 20fps, I should see my GPU load drop? That does kind of make sense, but I’ll need to test to see. 60fps seems like a sensible upper limit to have, although I do have a 120Hz monitor, I never see frame rates like that in game. I think the highest I’ve seen is around 80fps.

Yes, and it’s quick an easy to test. Also, I’ll set 120 for you as it’s your monitor Hz;, and will display my fps to be sure. As you can see the loading screen, the menu, the hangar, all that are lighter on processes so it run at insane speed and make heavy load and too much fps and useless stress on your gpu (514fps in loading for me and I have a lower/mid end machine!).

Edit: but if you can stand with 60Hz, that’s seems a good compromise with your 80fps and will get some fresh air to your system.

Interesting. I set mine to 60fps, specifically for MSFS, and not globally.

My main menu is now sitting at around 46-53% GPU now, and the same for the hangar.

Oddly, the world map, which is the view I thought was going to be the thirsty one, sits pegged at about 34%.

Yep, only for MSFS like me. First time I use the NV fps limiter, usually I use the Adaptive Vsync which lock at 60fps if above and remove the vsync if below. But with MSFS it produce a stutter each time it set or remove the vsync so I tried the limiter. Good surprise as I don’t have any screen tearing below 60, don’t know why.

You want GPU usage to be as close to 100% as possible.

Your GPU temps going to over 90c+ means you have a cooling issue. Most GPU’s have a decent cooler on them where even at stock settings it will barely go above 80c.

Its possible your GPU may just need some fresh thermal paste applied. Otherwise, there are other factors causing your GPU to get such high temps such as poor airflow into your case.

I agree and I know I’m asking too much to my GPU with the OC I apply. No problem in winter but nowadays room temp is above 30 degrees celcius and I should lower my OC (currently Core +150 at 2126 MHz and mem +400 at 5400 MHz). That give me extra fps I need and overheating is not really a problem with usual usage and my 60fps limiter. Anyway I know I push a little to hard. Its a GeForce GTX 1080 EXOC 8GB GDDR5X 256-bit, pretty happy.

There are a few GPU coolers available that might help. The 2nd in the list in the link below is quite cheap (AUD $49) and apparently effective, but does require the purchase of a liquid cooler as well.

I also found i could chop a few degrees off my GPU temps by:-
. Optimising my case fans. At 100% my gpu was venting most of the heat to the middle of the case. I just added a fan at the top to vent this heat. And general rule is to balance fans in against fans out. Ie 2 in and 2 out, not 1 in and 3 out.
. Using a custom fan profile in MSI afterburner. The std fan profile used by the card doesn’t ramp up the fans until the GPU gets really hot. I tuned the fans to give me an extra 500rpm at 100% which saw onky a small increase in noise.

After these 2 changes my 80c+ at 100%, dropped to about 74c. All for no cost as the extra fans came out if my old PC.

I also water cooled my CPU (for AUD $99) which saw a 20c drop in CPU temps. This had no effect on GPU temps, as getting case fans right meant all the CPU heat was being vented effectively to start off with.

It was also in a friendly conversation on THIS thread about 10 posts before yours, but thank you anyway.

My RTX2080 has quite an aggressive fan curve set via MSI Afterburner that’ll reach 100% fan speed @ 75C and sits at 99% usage in flight quite happily at sub 70C
My front mounted AIO has 2 fans, 1 of them blowing onto the GPU. I also bodged a fan pointed directly at the VRM on the motherboard. And 2 exhaust fans (1 back and 1 top)
And finally I perform maintenance on my PC every 2 weeks, giving it a good clean with anti-static brushes and a can of compressed air to make sure temps stay optimal.
