SU 10 is out!

You had the recent studio driver but went back to the GRD? Because of CTDs? And with the studio driver you didn’t get proper multithreading in DX12?

The DDU-ing was mostly because my installation in general after updating both the sim and the driver wasn't working well. So I figured I'd DDU the driver and start again (as I couldn't exactly undo the SU10 update). As I was doing that I thought I'd drop back for the clean install to the recent GRD anyway. The CTDs were just one of the problems I'd been getting with SU9, and that's about the only thing SU10 seems to have done for me - cure them. As for the multithreading - no, I wouldn't say the original driver achieved that much as far as that went.

Once NVIDIA release the Game Ready driver with the fix, Asobo will release a patch that will unlock the memory manager for NVIDIA cards again. Right now the latest Studio driver shouldn't create any difference from earlier versions because the memory manager that was causing the artifacts remains disabled for now.

From the patch notes:

 

So you know as a fact that the new Studio drivers with NOTES: on MSFS within the release notes on the new driver will not have the any benifit and are still disabled on Asobo's end?

Interesting!

From the patch notes:

Not wanting to disagree with the master!    But Matt Nischan himself said it would trigger automatically with the new driver, not needing a patch, and also, the studio driver release notes mention MSFS and fixing the DX12 artefacts.  So, my question is, were the artefacts in DX12 caused by the bad memory management?  I thought they were.

In the Release Notes for the current Nvidia studio driver -- Were the DX12 issues for MSFS mentioned as "known issues" or as "fixed issues"?

Ah sorry, I didn't see that. Thanks for the heads-up. I'll remove the misleading information.

As far as I can tell, the artifacts were caused when the memory manager attempted to use more VRAM than the allocated amount, but only on NVIDIA cards (which is why mostly those with 8GB VRAM were seeing the issue). I don't know whether it's the memory manager's fault or something on NVIDIA's side, but if it takes a driver update to fix it, it's probably the latter, especially since nobody on AMD GPUs saw the issue.

Ignore what I said, I was mistaken apparently. One way to tell for sure that the Studio driver is triggering the memory manager is whether MSFS can use more than 8GB of VRAM, since I saw reports on the official forums that, after it was disabled, VRAM usage was capped to 7-8GB.

What’s your theory on what we’re missing from the initial beta? Is it something from Asobo, Nvidia, or both?

It’s confusing indeed, as we just saw from Chaotic’s (now redacted) post, which contradicted what Matt said yesterday. 

Just finished reading a thread on the official forum, where the confusion is complete. Some are adamant that the driver referred to in the release notes must be the game ready driver, as the studio driver was out before the release notes.

At this stage I don’t know what to believe, other than my own observation that DX12 is smooth with the studio driver and it was not without it.

[bobcat999 8,484]

@ChaoticBeauty  No problem!    And I agree with your summary of the situation.  Logical!

The question is, where exactly are we?  (not necessarily asking you by the way - just rhetorical).

Does the studio driver only contain part of the DX12 adjustment, or all of it?
I can understand why people expect this to happen in the game ready driver, as that is what Nvidia normally do - it is strange when the fix is released in a studio driver, but only Nvidia will know the answer to that.

There is a thread over at the official forum (that Cpt_Piett mentions above) that would give anybody a headache, with some people crying out for a moderator or MS / Asobo representative to clarify the situation. It makes it worse that some people now report excellent results with the studio driver, and some don't.  of course, this may be down to individual set-up's and PC specs.  

Time for me to get the paracetamol out!

I’ve been getting “dedicated VRAM in use” of over 20Gb with the studio driver, reported by HWiNFO.

Thank you for the confirmation. If you're getting smoother performance too, it sounds like it's working. Enjoy!

I think the other thing to keep in mind is the DLSS "3.0" conversation with triple and quadrupling frame rates in existing titles is exclusive to the new 4K cards regardless of driver version.  It's HW dependent. 

So if you are thinking "DLSS+DX12 my framerates should be skyrocketing" that's not the case... The Nvidia videos were DLSS 3.0 on a 4K card which is where the "massive" gains Nvidia was showing were coming from.  

Memory management and smoothness/stuttering may still benefit with DLSS/DX12 but we want to make sure we don't confuse/blur/overlap the conversations...

Given your VRAM allocations, it seems the new memory manager is working for you, but you're still not seeing the level of multi-threading and performance gains that were in the initial beta... correct?  Which says that there's still something missing.

ps. Weren't you promoted to Admiral? 😄

So; more superb Asobo communication then. They could clear this up straight away with a simple statement regarding drivers.

I'm using the most recent studio driver. I'm still using DX11, however.

Is there a major difference in performance in using the studio vs the gamer edition?. Thanks! 

I think a few others answered you already.  For DX 11, you don't need the new NVidia drivers at all. The Studio driver is for using DX 12.

As for the differences, various sites will tell you that the performance for both drivers on games is the same. For me personally, I am waiting for the Game Ready driver. But if you already downloaded the Studio driver and it works well for you, just keep it, IMO.
