[Fossbytes] Microsoft Developing A Windows 10 “Game Mode” - Page 18

I'd like to add that there are definitely some regressions in Windows 10 that make several games unplayable, while they run just fine on Windows 7 with the same hardware. I currently experience that with Borderlands, Hawken, and a few other UE3 and DX9 games. In addition, there's a 4GB virtual memory limit for the DX9 feature level runtime, so any game that uses DX9 and needs to allocate more than 4GB of virtual memory runs into that wall and displays really crappy performance.

And there are several games that ran just fine on Windows XP but are unplayable on Windows 7 with the same hardware. The most notable one that I personally experienced was Juiced that ran perfectly fine on my at the time, 3GHz Prescott P4, 3GB RAM and nVidia 7200GS, but on Windows 7 it said I needed to install more than 256MB RAM and wouldn't launch.

 

This is something that has happened with previous Windows releases and will continue to happen with future Windows releases. Some games, especially older ones not working on newer versions Windows releases isn't a Windows 10 exclusive problem.

I get that, but what puzzles me is why Microsoft put a hard lock on the virtual memory allocation for DX9 games on Windows 10 and Windows 8/8.1. There's no reason do to it, and there are also strange variations in what's allowed in the different feature levels. DX9-03 is stuck at 4GB and supports 4K textures and shaders, but DX9-01 supports only 2K shaders while allowing a larger memory pool, for example. I know that the people working on Windows 10 and DX12 really don't care at all, and that's what makes it so frustrating.

 

I, basically, would need to run a Linux distribution and make use of KVM/Qemu to run different versions of Windows that are more suited to the games I'm trying to run, because Microsoft's latest OS has less backwards compatibility with some older games in my Steam library, many of which will never see patches to make them work on Windows 10 precisely because the different DX9 feature levels have limitations that make no sense. 

 

For all of the abstraction that Microsoft does to keep software working on Windows 10, particularly with app manifests making every old program think it's running on Vista SP2, it irks me that some UE3 engined games need their lighting models turned off to return to the same performance I saw on Windows 7.

a lot of DX9 games are 32 bit which is limited to 4Gb, no?

They are, but D3D9 on a 64-bit system can allocate more than 4GB of virtual memory for use in games and applications, some of which is in RAM and some of it in the drive cache on C. Some games like Crysis had a PAE flag you could enable with a command line argument, and it would use more than 4GB of virtual memory on a 32-bit XP system. That was an early workaround, which stopped being a requirement when 64-bit Vista shipped.

 

On my system, fully patched, with the same driver versions, running the ENB VRAM size test tells me that the DX9 feature level on Windows 10 has a limit of 4093MB, while that same test on Windows 7 maxes out at 16GB. DX11 on Windows 10 tops out at 28GB, the same as Windows 7. For some reason, Microsoft hard-coded that limit in for the DX9 feature level that games like Borderlands and Hawken call, and it makes them run like ass.

I've got a better idea for game mode: Vulkan under Linux.

Good luck with that one Gabe. thumb.gif

Start Menu - Settings - Says Game Mode is on

but I have read you have to wait for game bar to open when you launch a game, then go into settings, and manually turn it on for each game.... so which is it? >.>

I can't test myself because I have no games installed.

What the difference between Game Mode and High priority?
post #180 of 187
Microsoft needs to stop with the Xbox shilling and just have an option to link to an exe to turn on game mode instead of using the game bar - which doesn't even work in fullscreeen exclusive mode.
