Windows 10: Windows10 nVidia vram usage

Hi folks,

Does anyone have any idea why Windows 10 deserves so much vram on nVidia GPUs?

Why can’t we use almost all of the vram like on Linux? 10-20% of the memory is apparently system reserved. Why is that? Is there a way to avoid it?

Thanks

Games use too much vram after upgrading to windows 10

After upgrading to windows 10 the vram usage in games have increased significantly, like in windows 7 i played gta 5 with high textures and vram usage would never cross the 2gb limit but now even on normal texture the vram exceeds the limit, i tried reinstalling
the nvidia driver twice and even used the old driver which worked perfectly in windows 7 but none of these solved my issue.

Even i tried to run it in windows 8 compatibility mode, but it didn't help.

Please help me out.

 

Windows 10 CPU usage 100% when Nvidia GPU enabled

I've had the same problem, and have exactly the same GPU model. I was able to set the drivers back to factory default, but any update I've tried (including the most recent) causes the massive cpu usage. I've contacted tech support for both Nvidia and Asus,
and followed all the steps they suggested, with no luck.

 

HD4000 RAM usage vs NVIDIA dedicated RAM

To answer your questions:

1. Every OEM is free to configure Nvidia Optimus the way they see fit. On some models, it's even possible to completely disable Optimus alltogether in the system BIOS and select a specific GPU (common on workstation grade systems such as HP's Zbook series), where others do not allow adjusting Optimus setups from the BIOS. In such cases, you can either have outputs wired to either the Integrated Graphics ONLY OR wired to the discrete GPU, with the eDP -driven panel for the laptop being the only monitor powered by the Integrated GPU.
   
2. Offloading programs to the NVIDIA GPU will markedly improve their performance, say games and rendering software such as the Adobe line of products. However, when in use, the discrete GPU will obviously consume more power and generate more heat. RAM usage depends on what a particular program does with it, and whether your computer is experiencing any form of anomaly such as memory leaks due to poorly written device drivers. Loads running on the Integrated Graphics, such as render, do take a portion of RAM for use as VRAM, but this is not something that should be of much concern in terms of utilization. What should concern you is whether you have dual-channel RAM. Integrated Graphics loves dual channel memory, and it can drastically impact performance in tasks such as video encoding (Intel QuickSync) and gameplay (if you use the IGP for that).
   
3. To check for VRAM usage, use a utility such as GPU-Z or Mark Russinovich's sysinternals process explorer. Note that GPU-Z separates the fields, showing discrete and shared VRAM usage, whereas sysinternals' process explorer pools the total available graphics memory pool as one.
   

Hope this helps.
