Why no Fullscreen?

[Deadlybudz]

I'm tired of chasing my mouse off screen and trying to find it. Fix this annoying garbage and give us exclusive fullscreen. Also, every single game I've ever played looks 100% better in fullscreen. RTX 3090 FTW3 ULTRA, ROG Strix Z690, 64 gigs ram, I9-12k Cpu, so its not my pc. Its runs weak compared to comparable games, fps would def be higher. Why does it say there is Fullscreen if none?

I play in Full screen all the time. Try hitting F11 when your in the game. Or going into the setting and Setting the Display to Fullscreen

There's no fullscreen mode on DirectX 12. Microsoft did a lot of improvements to Windowed Mode so it has the same performance as Fullscreen Mode*. Yes, there's “fullscreen-mode” flag on DX12, but it does the same as Borderless Window. Some games cheat around this by always holding the cursor and by minimizing itself when the game loose focus, those are not True Fullscreen Games because DX12 don't have true fullscreen.

Although I agree that they could've handled this better, it's annoying when my cursor goes off screen, this is something fixable. But, again, DX12 don't have Fullscreen Mode, don't matter what the game tell you, it'll just cheat for you to think it is**. There's no performance difference for games running under DX12.

*: at least that is what MS claims, they dropped support for Fullscreen Mode and that's it, it doesn't exists anymore for DX12 and on.
**: Some games run on something called D3D11On12, which is a compatibility layer, they're running under two different APIs, those can run on Exclusive Fullscreen Mode because they're DX11 games running under DX12 with some hacks, one example is Cyberpunk 2077.

But Fortnite has DX12 for Lumen and stuff and has fullscreen, is not about DX and is more about developers, read that GoW had some issues implementing vsync, hdr and all of those options so they better opt for windowed, nothing to do with DX12.
Anyways I'm here because I want to do RSR for about 85% of 1080p so it looks amazing and gives performance. FSR 2.0 freaking hate the ghosting, FSR 1.0 in "Ultra Quality" is around 77% of the screen and I want 85% so the image is waaaay better.
Plus FSR 2.0 is heavier to do and why would I want to do an extra FSR 1.0 algorithm when I have in driver RSR for no extra cost.

It's not actual fullscreen, it's something called Flip Mode which is just a fullscreen optimisation for windowed applications. It has two varients, iFlip independent (supports vsync) and iFlip immediate (no vsync support but better latency).
Developers used to have to manually maintain control of the display adapter (the GPUs representation in software) with exclusive fullscreen, if they didn't and the adapter was lost (which happened a lot in exclusive fullscreen) they'd have to restart it or the game would just lock players out and they'd have to restart their PC. If you've ever had a game go completely black and then crash, that's what it was.

2024 AND STILL NO EXCLUSIVE FULL SCREEN. PLS HOGWARTS LEGACY. COME ON. PUT THAT FEATURE PLS OPIJASDPJASD WTF. if the comment above is true about dX12. then pls have an option for HL to run on DX11 for it to have EXCLUSIVE FULL SCREEN. ITS NOT 100% SMOOTH AND IS STUTTERY

Exclusive fullscreen is obsolete and breaks more things than it could even possibly fix.

That wouldn't change. Flip model is significantly improved over exclusive fullscreen - if you're stuttering currently, hacking in a fake exclusive fullscreen mode isn't going to do anything for you.

And adding a DX11 mode will make the game run even worse. Remember that DX11 is still largely single threaded for drawcalls and most of everything else it does. They'd have to completely rebuild and reoptimize the game in order to not get CPU bound on multicore CPUs. DX11-based games that have good multithreading have had an absurd amount of work done just on that aspect alone, hence why there aren't very many.
