It depends.

With a low level api, it is much more complicated to manage Vram, it may take a lot of time to fix brain damaged stuff, however once you succesfully implement and work on a low level api fixing stutters and fps is straightforward. 

I wonder what is the time frame for dx12 in msfs. High level to low level api is a really long task. Unless somekind of low quality port is done which i highly suspect aint gonna happen.

If they wanted to use DX12, they would've decided for it in the beginning of development, when DX12 was already 2 years in the market. To think there will be a DX12 switch in the near future is very naive. They took the easy way, and now they get the check.

Well, my heels are currently on my pedals, as I just landed the Cub Crafter X Cub!

Touching the ground is the easy part, the rolling out is where you see a smart pilot. Did I say ground loop ?

I actually just made a discovery. It IS possible to ground loop in MSFS, whoever posted that it was not possible was wrong!

Good point for the new sim in my book.

Well,it was less of a ground loop, and more of a "I just crashed into Ankor Wat, my bad."

word not allowed X Cub brakes! I've never crashed into a 700-year-old Khmer temple IRL, so I don't know if Asobo has modelled the physics realistically.

I know some former beta testers are having better performance in the RC than the beta, but for several of us, it is just the opposite. I have a 4790K CPU, 1080Ti GPU with 32GB system RAM.

I fully realize that my CPU is not optimal by modern standards, but it worked very well in alpha and beta with many graphics settings at high or even ultra. I had occasional stutters in complex aircraft (A320), but nothing deal-breaking.

Now, in the RC, I am having massive stutters even in the analog C152. I have actually lowed my settings from what I used in the beta. It occasionally freezes completely for several seconds, CPU utilization goes to 100 percent, and GPU utilization drops to almost zero. I’ve even seen the GPU downclock to P8 memory speeds in the midst of one of these long pauses, as monitored in NVidia Inspector.

At best, I see 60 percent GPU utilization, while in the beta, it often hit 100 percent.

Something definitely changed in the RC version. After removing the beta, and before installing the RC, I did update my drivers to the latest 452.06 - I am in the process of rolling the driver back to the July edition that I used in the beta.

I had the problem with CPU going to 100% and the GPU not doing much. After I got that sorted out the sim runs smooth and I'm having tons of fun. My i5-7600K is staying in the low 60's which means I have room to OC if I want. Maybe when we get out of this heat wave.. It's my 1070ti that hates me! I hope it doesn't die. It is getting on the warm side, fans a blowing.

In another thread, people have pointed out that the manual cache options seem to create stutter. Did you change any of the scenery caching settings?

How did you solve it if I may ask? 😱

On installation, the sim created a default cache of 32 GB, and put it on the C drive. It appears that it sets the size equal to installed RAM. The major stutters were with the default cache. I just now moved the cache location to the SSD where the sim is installed, and increased to size to 64 GB, and it appears performance is a bit better. I also rolled back my drivers to the 451.77 version I used in the Beta, but GPU utilization is still much lower than it was in Beta.

What did you change to fix the GPU under-utilization problem?

Performance is fine for me (Ryzen 5 3600, RTX 2060, 16gb Ram), except the largest cities. There is an occasional pause when loading some areas having to do with scenery loads, but it usually only happens once right after the flight starts (if it happens at all). The sim performs exceptionally well when there aren't too many buildings.

Seattle is rough in some spots and NY is really bad, but that's to be expected. I'm in 1920x1080 though, but running most things in ultra, I turned some shadows down.  Reflections and Waves to high not ultra.

I changed texture supersampling to 4x4, grass and bushes to high instead of ultra, and same for buildings (high), otherwise mostly ultra. You don't really see the grass and buildings that close up most of the time, and the improved performance is worth it. The buildings still look fine to me.

Generally, the Sim performs really well if you are getting at least 25 fps, anything lower and starts to get a bit choppy. Not really getting stutters other than the highest detail areas like downtown NY (a little, depends).

I'm not having any issues with GPU usage, here are my performance metrics flying around NY...

CPU: 40% to 65%

GPU: 90% to 98%

Ram: 95%

FPS: 15 to 50 (only 50 if on far outskirts not near buildings)

Avg FPS: 20 or so

Nvidia Driver: 451.67 (RTX 2060)

There are so many buildings in NY though it's silly, I don't think people with RTX 2060's / 1070's or lower should expect great FPS around NY without lowering settings. Most other cities are fine, a few other very dense ones have similar problems.

I dont have any issue with performance. Running with 40-50fps on blended high/ultra settings.
