NVIDIA INSIDER Preview Driver [450.99][Standard]

450 - 451 driver brunch will be released in jun or july.
Next Nvidia game ready driver will be from 445-446 brunch. They said, that at least one more driver will be from older brunch.

450.99 for now look nice, pretty stable. No memory leak in Dx12 like 450.12, full support all vsync options (450.82 have only vsync on and off). No blue screens or crashes in games, average and min performance slightly increased (Dx 9-12, Vulkan, OpenGL).

 

Actually playing Deadfire, the second game. But just finished the first, only a few days ago. No problem.

 

That's why I used hwinfo for the other measurements. Even if its visual only, still an issue nevertheless?

 

Task Manager shows D3D GPU usage which has limitations with async compute and CUDA/OpenCL.

 

Refer to the topic title: preview, for Windows Insiders, developers (in this case, mainly DX12 developers who are interested in new DX12 features, for preliminary testing).

 

Yeah speaking of Windows it gets a bit blurred same as those Windows insider builds as something like "Oh new build." and a lot of people end up installing and using it like your standard beta but that's usually a thing that just happens and the feedback here and other forums, NVIDIA's Reddit I suppose and also the GeForce forums might still be helpful for issue tracking and testing even if it's not as structured as an actual problem report or test environment and setup.

Development preview drivers for DirectX 12 Ultimate but with WDDM 2.7 and Windows 10 20H1 of course regular users would want to try the new features like GPU hardware scheduling and with no NDA or registration process for the download NVIDIA has taken that into account no doubt thus it's just a regular download process with some notes in the description for what the driver is for.

 

This is not a insider driver, insider driver comes from
Windows 10 Insider Preview Fast Build , latest insider driver is 450.82.
copy a phrase from someone else!

 

G-Sync seems to be borked in this release. Keep getting the occasional, white-ish flickering and second long black screens. They are gone when G-Syc is disabled, especially 3Dmark seems to be affected. Hope this won't occur with the official WDDM 2.7 drivers next week.

 

A little reverse engineering gives amazing results:

unpacked nvcuda.dll:
https://drive.google.com/file/d/1f_umCeGEpfPJOVCZXa9ZAcXInzhuLoTz/view?usp=sharing

I unpacked the nvcuda32.dl_ and nvcuda64.dl_ files from the folder "450.99_gameready_win10-dch_64bit_international \ Display.Driver", renamed them to "nvcuda.dll", placed them in the directory
C: \ Windows \ System32
and
C: \ Windows \ SysWOW64.
The system now detects CUDA files

UPD: Graphics settings "GPU Water Simulation" and "Bokeh Filter", which I reported recently in this thread, which disappeared from Just Cause 2, immediately appeared after that

 

Well, it fixed my freesync related flickering black-bar issue:
https://www.nvidia.com/en-us/geforc...kbar-like-flicker-at-the-top-of-the-screen-r/
It's quite difficult to create the right conditions to trigger it but so far I haven't been able to trigger the flicker even after forcing the GPU to switch clock constantly using the FIFA 20 menu.

 

Wrong.

450.82 was a dev preview driver (and later pushed out on WU)
450.99 was an Insider preview driver (obtained on the fast ring) and later released on the dev preview site.

 

The files you replaced are loaders or forwarders, clearly Just Cause is in the wrong as its trying to read the version from a hard coded path,

as an alternative you can copy nvcuda32 into the game folder as nvcuda.dll

um. don't use gsync with 3dmark?

 

I noticed that this drivers are a bit slower when particles or explosions hapen on crysis 3,assassins creed odysey. But not al bad news doom eternal runs fine wolfnestein 2 also more smooth,mafia 3 runs like crap frame drops anyware i loock. But in assassins creed i lost 2 fps but gained more stability now my average its 59 fps but realy smooth. Valorant also runs very well.

 

I dont have hardware scheduling on but of assassin creed odyssey works great. Try turn of hardware scheduling.

 

gsync is working good for me with this driver

 

OpenGL titles with hardware-accelerated gpu scheduling gets noticeable boost, maybe because HW scheduling reduce API overhead.
Vulkan and Dx games with HW scheduling gets improved stability - less stutters, freezes and frame drops ( also, min and average FPS is slightly improved across titles, not as huge like OpenGL but noticeable).
451 is still under developing, but on final stage.
WDDM 2.7 aka 450/451 brunch will be some time in june or july.
Probably next week will be 445/446 driver - Nvidia member said, that they still have at least one more driver from 445/446 brunch.

 

So far works like a charm not even noticing this is developer driver !

 

Nvidia's opengl driver is already near-zero overhead.

 

So installed 2004 and these drivers today. so far have only played Fallout 76 and GTA5 both seemed good no issues with performance.
But with GTA5 in the loading screens, I would get a black flashing over the images, didn't occur in gameplay or in menus. Just on the loading images.
Hardware Scheduling on. I will test later with it turned off to see if it makes a difference.

 

thats gsync/vrr related, the loading screens don't push continuous frames, only updates to the images are displayed.
