Terrible Performance after SU8 with RTX 3080[SOLVED] Might be Useful for People Having Performance Issues

I don’t really know to be honest, can’t really tell which one of the Nvidia Control Panel settings did this effect but I’m so scared to try them one by one :smiley: But I’m %100 sure that Nvidia Control Panel settings changed everything for me in the game. I don’t think balancing CPU/GPU because my settings are the same as the one of my first posts that I shared for my in game settings.

Yes when you find a good spot there’s a huge reluctance to change a thing! The 30FPS gives me the fluidity (along with a quieter GPU fan!) I like when panning wildly about in the cockpit, but it’s very interesting to see that it works for variable FPS up to 60 too. I’ve seen all kinds of claims on here about NVidia CP settings, it’s also another area where people seem to have entrenched views and a wild variety of settings. Do you have HAGS OFF too? It’s HAGS off for me in Windows but Game Mode is ON. Again I’ve seen varying claims about these two. In relation to stutters.

That’s exactly the same on my end. I’ve also read couple of suggestions that suggest to turn them on/off, but this is what I’m using at the moment :slight_smile:

Thanks sooo much, i think this just solved all my issues!!!

We’re glad that it works for you !

I had it in 144hz and the geforce settings were all standard. Changed to your settings you advised, Turned up the resolution in the options to make the gpu work a bit arder and bingo, solid 30fps constantly.

All credit to Pilot Pete wherever he is. Just pass the info on for others to try. The more people we can try to help the better. FS shouold be able to be enjoyed stutter free irrespective of the hardware combinations we use.

So I saw better performance last night at Charles de Gaulle as posted above, but this morning it’s no quite as good as last night, so I think the servers play a part.

I actually tried low latency mode on, but turned it off again as it didn’t seem to do much and my system is more CPU limited than GPU, and I believe low latency mode is there to help GPUs.

The bigger result from @BragRaindrop933 was by turning TLOD down a bit, and pushing render scaling up to 125 @ 4K - this got me around 4-5 fps and the take off roll at Charles De Gaulle doesn’t go below 22 FPS so appears smooth.

Did you try the 30FPS/60Hz tweak for smoothness? It seems to drop CPU/GPU loading a good bit for me too.
Also keep all traffic down a bit as it’s CPU intensive. It may well be your CPU is the bottleneck, but keeping it from being limited by dropping it’s load while keeping GPU busier is key when mainthread limited with a high end GPU.
I suspect that each sim update change CPU/GPU loading a bit so everyone who isn’t already optimised ends up seeing issues without realising that CPU/GPU balancing may be required.
Look up ‘32ms latency’ on here Grabber523 has done a lot of ground work for us all on balancing CPU/GPU loads and has been a great help in understanding the issue. You may want to further optimise/balance to target the 32ms GPU render latency as that seems to be his recommendation, although that could just be for the 30fps use.
Anyway the main part is having the awareness of how to reduce mainthread limiting, you can further your research from there.
ps. mornings may just have more AI/live traffic at LFPG than evenings. It could be a factor on your CPU.

So my vsync is set to 30 fps in the game, and NVCP is set at 60hz under “change resolution” tab. I don’t have an option for “prefer max refresh rate” anywhere.

So hopefully those are the tweaks you are referring to? Except with low latency mode turned off as I’m more CPU bottlenecked.

You could also try with VSync off as @CkTheWinner has seen his system free up to where he’s happy just with the NVCP changes. Also make sure HAGS is OFF if you haven’t turned it off yet. Windows Display Settings->Graphics->Change Default Graphics Settings->Harware Accellerated GPU Scheduling->OFF (+restart)

HAGS is off :slight_smile:

All out of suggestions other than maybe a slight increase in gpu render scale see if you can hit that 32ms render latency figure. There are other hardware improvements like XMP if it’s not already enabled or even supported with your RAM, but you are getting into overclocking tweaks territory with that.

Could you let us know the FPS you are getting at JFK in FBW A32NX? Pan the camera around to see if you are getting any main thread limitation. I always wanted to set my TLOD beyond 200 at JFK but my RTX 3080 and i7 11700k couldn’t handle it.

On the runway:
When pan the camera around it drops around 28.

After departure:

TLOD 200, which is the value that I always use + %70 dense AIG.

Thank you. And are you using Asobo’s handcrafted JFK scenery from premium deluxe edition?

I’m using Premium Deluxe Edition.

Do you have AIG traffick and if so, what percentage traffic do you use?

I get similar fps to you, but not when I’m using AIG or in sim traffic.

In all the images I sent into this topic, AIG is always enabled with %70 density.
