Are you DirectStorage ready?

Winrar is said to have faster unpacking than compressing, whereas 7zip has faster/better compressing than unpacking.

I tend to unzip more often these days so maybe it's worth the change. And then I unpack files WAHEY!

I will consider joining the Winrar gang once again.

Edit*

I have done some testing.

Downloaded the current version of Davinci Resolve which is 2.45GB. Needed to update anyway so two birds one stone.

Anyway,

Windows explorer extraction: 18.87 seconds
7-Zip: 8.5 seconds
Winrar: 11.15 seconds

So 7-zip wins at unzipping too.

Winrar uninstalled :cry:

Thank you my beta testing friend :D

As far as I know winrar dev has also ceased, so 7zip wins are only get to get better moving forward.

Did not know that. Makes sense as the version number has been the same for sometime.


Does anyone know if you password protect files with winrar, but uninstall that and install 7zip does it work?

Nvidia blog post today said that Ds1.2/RTX io improves game loading times by 5 to 6 fold.

And Nvidia also claims that ds1.2/RTX IO fixes game stuttering when stuttering is caused by the CPU

There must be a switch to add to the exe shortcut to trigger a run without using GPU decompression or any DS, just transfers the same data the old way. Someone will know :p

Usage​

BulkLoadDemo [-dir <directory>] [-model <filename>] [-gpu-decompression {0|1}] [-debug {0|1}]


The demo can operate in one of three modes:

  1. Default: by default, any .marc files in the same directory as the executable are loaded. Multiple instances of these are loaded in order to ensure that there's enough work to do.
  2. Single Model: The -model command-line argument can be used to specify a single .marc file to load. This mode is mostly useful for debugging a single model.
  3. Directory: The -dir command-line argument can specify a directory. All .marc files within this directory are candidates for loading.
GPU decompression is enabled by default, but it can be explicitly enabled/disabled using the -gpu-decompression argument.

The D3D12 debug layer can be explicitly enabled or disabled using the -debug argument.

Close the window, or press Escape, to exit the demo.

BulkLoadDemo.exe -gpu-decompression 0 (off)
BulkLoadDemo.exe -gpu-decompression 1 or BulkLoadDemo.exe (on)

So a 1.34 seconds difference given both are very fast anyway. Anyone with a SATA SSD will be perfectly fine as the relative difference is so small you won't need an NVMe SSD to leverage it for loading. How that translates to seamless rift transitions without stutter remains to be seen but I see it as a non-issue due to the nature of GDeflate. It's only a noticeable difference if a future game for example takes 10-20 seconds to load into the game whereas with DS1.2/RTXIO enabled it does the same load in 5-10 seconds - Both scenarios are extremely unlikely given most games load so fast anyway.

The Last of Us being the only exception as we all know, but that has known CPU utilisation issues and puts everything shader comp-wise onto the CPU.
 
Here we go boys





RTX IO getting a good workout, loading faster than a PS5

About 170fps average with RTX4090 at max settings, RT on with DLSS3

As usual Nvidia only show DLSS off vs DLSS 3 (frame gen obviously) on, which shows the biggest difference. They don't add DLSS 2 on with frame gen off because the difference between that and DLSS+FG on is much smaller. It's silly but it's marketing bs 101, to show the greater difference only. DLSS Quality alone will get over 100fps at 4K going by the baseline metrics shown in the raster sections of that video.

This is great news for those at 1440p, you'll get over 100fps with DLSS off lol if you have a 4090, or use DLDSR at 4K to get the best image quality along with the best framerate.

More importantly this also highlights the scaling factor of the engine and optimisation.

It's been confirmed that R&C has DLAA so that's how I'll be playing it :)
