This is extremely helpful. So, the CUDA Cores are not enabled in MSFS 2024 because many cards do not have them. One has to process that observation… why not make it an option for those that have the cards?
I have not done graphics coding for some 10 years but I cannot see why this program is knee capped.
In astrophotography (why I bought this machine in the first place) the CUDA Cores are essential to run AI for noise reduction… runs at least an order of magnitude faster…
Anyway, seems like my system when I turned down some of the realism useless settings like the trees runs fast without using all the Core CPR resources or for that matter the GPU resources.
Seems to me also like they have set this to run OK on 32GB RAM and 8GB of GPU memory. I am running with 64 and 8 respectively and 32 and 7 are used.
Lock MSFS at 30fps and combine with rubber duck Lossless Scaling (Scaling Off, Frame Generation LFSG2.3 + 2x mode) and you can easily get a smooth 60fps experience with all visual balls and whiffles.
+++ Use DLSS Swapper to force MSFS to use latest 3.xxx DLSS version - this instantly gives you 5fps.
I set up the frame generation Dlls, set hardware scheduling in pc settings and rebooted. But the frame gen log says I don’t have hardware accelerated? Need to do it in Nvidia control panel somewhere?
NVSDK_NGX_D3D12_Init_Ext
[09:49:51] [info] Hardware accelerated GPU scheduling is disabled on this adapter.
Had a busy day today flying a 787 from Philadelphia to SFO during dinner on AP. Made a nice completely automated Cat 3 landing and flew at 60 FPS after various tweeks. I then flew the C-172 from San Jose to SFO and got 80 FPS. This is after backing off on some of the settings that are useless.
I verified that I have the old DLDD 2.4.12 dll but not sure I want to change it out if there is no gain. We change out the tensorflow dll for cuda cores every time we upgrade our AI/astrophotography software and it gets old. Not sure I want to use 3rd party software to make it easy.
I am still irritated I cannot use cuda cores in the MS handiwork.
BTW I am not using my full 64GB of RAM (just 32) and only about 7 of the 3070 ti… the 172 uses less of both than the 787.
PS I thought the 787 was pretty squirmy until around Kansas when I realized I still had the gear down.
PPS Here is a little piece of local screen candy. The visuals are beautiful. I can put up with the tweeks if I get this.
PPPS This DLSS stuff if pretty bogus from what we do in astrophotography. You would be tossed out of the club if you upscaled a low res photo and said it was high res… such issues are common topics in astrophotography and there are a lot of very sophisticated scaling methods which I guess have their analogues in computer graphics. I run a camera with about a 9000x6000 pixel sensor and you do not get the same running 4500x3000 and upscaling x2… now if your are oversampled.. it makes no big difference.. but if your sampling is correct you are throwing data/resolution away. It computer graphics you do not need to worry about how in focus you were… and we do have resolution to spare… until you blow it up on a big screen… interesting stuff.
Obviously if you render lower resolution and upscale then you are losing definition, no amount of AI can know what the pixel should have been, it just has to guess. This is why many of us stick to TAA.
What I can suggest is to look in dev mode for what the sim is doing with the rendering. This will give you an indication of where the bottleneck is. Also look in task manager to see what your components are up to at the same time.
Yes, finding my ways around here. The DLSS essentially upscales what we call 2x2 to 1x1. It draws at 70-80 FPS in my C-172. If I switch to TAA the frame rate goes down to 45, which is similar to what I get with AA turned OFF. With DLSS turned on I can see the degradation a bit of some of the text on the instruments, which is more of an issue for me at my age than the scenery.
Thanks for explaining this.
PS At the end of the day, running at 30 FPS should be good enough… not sure that I can tell if it is any smoother than 60+ but I guess it gives you head room to avoid transient glitches.
PPS Looks like in TAA I am GPU limited… with the 3070 and the 8GB…
No issues in task manager, however…
I thought I tried all the anti-aliasing options, but I missed AMD FSR, so I chose that and dumbed down the TLOD and texture resolution a bit, and wow!!..now I’m up in the 90-100 range. I’m still suspecting that there also might be some inconsistencies with how fast the cloud is feeding data to my sim, but I’ll keep an eye on it.
Jumping in. I also see the large drop in fps in 2024 compared to 2020 with same settings.
VR
4090 + 9800X3D
TAA on
100 resolution (approx 3k x 3k)
High \ ultra settings
Example case 35-40fps 2024 and 70-80fps 2020. Settings are the same to extent possible. As another user said, big drop with no noticable benefit. Sticking to 2020 for now.
I have the same. Sometimes I get 50-60fps and then when I mess with the graphics settings and change some things it really screws up things. After I’m sometimes at only 5-10fps even when I LOWERED the settings. There clearly something wrong here.
Exactly the same thing here again. Sim had been fine for a few days - yesterdy and today, i’m getting massive VRAM usage and fps dropping to 5, lowering settings makes no difference.
It’s so variable and I assume this is linked to cloud bandwidth. The other night I was flying over NYC at 70fps, today I was struggling to maintain 30fps at Shannon with intermittent drops to 10 fps, very annoying.
I have an RTX2080 Super. I regularly get 60-80FPS in 2020 at 4K, but when using the C700 in 2024 frame rates are 17 near airport and 30 in flight. When I use a non-streamed aircraft the frame rates improve to 40-60FPS and remain stable. I believe that the main issue is the streamed aircraft. I have tried other streamed aircraft besides the c700 and see the same low FPS rates.
