Hi everyone! 

So I am very intrigued at the fix below that is coming soon. 

PC Simmers with graphics set to Ultra will experience this when panning the camera around very quickly. We are working on a new option that will allow you to customize how much off-screen scenery will be cached. We are aiming for this to be released on August 24th (World Update 6).

When I have a LOD of 2, it is fairly smooth, however, I get a lot of blurries. When I have a LOD of 5, things look better and sharper but I get a lot of stutters when I pan around. My question is, how is that slider going to work and do exactly. And what do they mean by customize how much off-screen scenery will be cached? Will it put some stress on my ram or GPU? Will this slider help me get smooth panning at a LOD of 5? I'm not quite sure how this is going to work. 

If anyone understand this a bit more than me I would appreciate the clarification. Thanks!

Now if you notice, what is loaded into your GPU memory is what you see exactly in the screen, so I think when you pan the camera, the process of loading from RAM into the GPU memory kicks off, if I understood, the popup is because of the latency of loading from RAM into the GPU memory process. Now that slider, if I understood it correctly, will cache more data off screen into the GPU memory which theoretically will put stress on the GPU which is expected (nothing comes for free). So yeah as result, I don't think you would run LOD of 5 and at the same time have too much cached in your GPU. At some point, you would need to find a middle ground between visuals and popup.

For me at least, setting a high LOD such as 5, the stutters are not a fault of the sim - my hardware is simply not up to the task. Your PC specs are miles ahead of mine but you might still be bumping into a hardware limit.

I am living with LOD 200. One thing you can try: I have always been doubtful about the benefits of using the scenery cache and it has been off since day 1. However in the past week I have noticed that terrain popping seems to have been improved (i.e. reduced) by setting a small cache, in my case, of 4GB. I use Track IR and it was a bit obvious after SU5 and a bit ugly really but now, I don't really notice it anymore. If you have not already set up a cache, give it a try.

Thanks for the reply @omarsmak30 @RaptyrOne!

So this is my performance with settings mixed between ULTRA & HIGH with a terrain LOD of 5 and object LOD of 3. 

I will also try setting up cache. Is there any reason why i wouldn't want to use cache? I have very good internet speed and a lot of SSD space. Could this help with the blurry and slow loading textures? Thanks again!!

You have render scale turned up and using lod 5. It's obvious your pc can't keep up. The goal is to keep red bar green. That's why you are having stutters. Turn your settings down

I don't think so because it's ONLY when I pan fast that I get stutters. If I move around slowly it's fine and when I fly it's very smooth. Also, I lock my frames at 45 and it mostly stays there.

Here is a video. My performance is amazing when I just look forward and fly. Two things bother me, the stutters when panning fast and the blurries/terrain look like word not allowed.

It's worth a try setting up a cache. It takes two minutes. Then go and fly and test. If it makes no difference, you can always switch it off again. I don't think there are any real negatives for setting a cache and Asobo recommend a minimum 8GB I think (stand to be corrected) but previously I saw no point and if there is a negative, it is that you are constantly writing data to your SSD. That is using CPU cycles and if there is not percievable benefit, why have it on. That was my logic until SU5 came along. Now the popping when I look around seems to be almost gone - not completely - but it is better imo.

But as @devgrp says, you appear to be pushing the limits of your PC and that will bring stutters. Also try setting Vsync on and 30 FPS (not 45). I have a far lesser machine than yours and I have LOD 200 and a mix of High and Ultra and with Vsync on, limited to 30FPS, it really is smooth, even in pretty dense areas. So much so that I am in no rush to upgrade to the RTX3070 that I had my eye on.

It looks like you have plenty of GPU RAM left, so LOD levels shouldn't be a problem, but that won't stop you getting performance related issues due to 'limited by main thread' etc.

If you have plenty of space on your SSD, it wouldn't hurt to set a 5GB rolling cache.  It may help, although the slow loading and blurry textures seem to happen at random, even for people with fibre connections and RTX3090's!

Don't forget to flush the cache after every update though.

EDIT:  As Raptyr above.  Our posts crossed.  I also agree with him that limiting to 30 FPS is generally a good think if you can't make 60.  It may help the blurry texture issue also, but not always.  I seem to get it in specific areas.

@bobcat999 @RaptyrOne Thanks!

I set my FPS to 45 and seems to work well as seen in the video above. When capped at 45fps, my GPU is only being used around ~72% and my CPU around 30% to 50%. So I should be able to stick to 45fps, no?

Your CPU is struggling, that's why the stutters. It's limited by main thread and lod is processed by the cpu not gpu. Like I said you want to get the red green at all times. A gsync monitor may help. I have a 2k gsync monitor and all my bars stay green everytime 

Here is a free tool you can use to see how much stuttering you have and performance https://www.capframex.com/

Thanks, my monitor is 1440P with GSYNC. I tried locked at 30FPS with VSYNC ON and here are my results:

Also, I feel like it's even less smooth than locked at 45.

That's because instead of loading assets for the entire visible area of a circle, after SU5 the sim loads them only for your current FOV. If you notice, regardless of the LOD settings (= the radius of the circle), the RAM and VRAM usage doesn't go past 6 GB, while before SU5 it was common to see 16 GB of RAM used even with LOD 100 on PG areas!  

Therefore you can have very good performance even with insane LOD settings as long as you go ahead, but when you rotate the view the sim has to load many assets from the storage unit, or even worse from the Internet, hence the stutters.

The 24 August fix should allow us to decide how much off-screen scenery will be loaded into RAM (or VRAM, it's not clear), and this should eliminate assets pop-in while still maintaining a better framerate than SU4 (because the glass cockpit gauges are not on the main thread anymore, and that alone was a big improvement).

Let's wait and see.

Don't use an external program to lock your fps. Enable gsync in the Nvidia control panel and lock at 30 in the sim. You gpu should be working at 100 % at all times
