Custom Resolution Utility (CRU)

[spikespiegel]

I'm trying to get Detroit Become Human to work with the custom resolutions, but I still haven't had any success. Same thing goes to Final Fantasy VII remake intergrade. I can make it work with WRC9 rally game.


This is the result I'm getting, the in-game image does not occupy the entire screen, but it's funny because it's not like the resolution is changed, because when I move the game's cursor around, I'm able to move the cursor around the entire screen. It's like there's something else I need to do in order to get the game's internal resolution to fit, not just its window. Detroit Become Human uses Vulkan.



I've tried to make this work with many custom resolutions, from 320x240p up until 2560x240p, the result is still the same. Inside NVIDIA panel the only scaling option that works for me with every single game is Full Screen. My video card is an nvidia and it doesn't have interlacing.

All the 240p custom resolutions are set with automatic CRT, Progressive Scan. The settings are working for all the emulators (including retroarch), except Yuzu that only accepts 320x240p, and they work for the for the majority of the PC Games.

My CRU settings are as follows:

Just wanted to say thanks for this.

I actually started using it maybe in a weird way (due to the global gpu shortage) with my LCD panel @ 60hz:

I DOWNCLOCK my LCD panel to "virtually" overclock my GPU and CPU -- let me explain how this works...

1) I downclock my LCD panel from 60hz (actually 59.95hz) to 49hz (Actually 49.003hz. Any lower and I notice Windows text starts getting blurry -- otherwise I could've gone down to 48hz... which is actually 48.003hz for me, which still looked smooth enough, but again everything got a little bit blurry. At 47hz the Windows mouse cursor movement begins to get noticeably choppy in addition to increasingly blurred text).
2) Then I use RTSS to lock my framerate to 48.99 (to keep input lag low due to starving the vsync buffer -- this is a neat trick I and many others have been doing for many years but RTSS is best suited to doing this because it's so precise).
3) Enable VSYNC in game (I always enable vsync no matter what because I hate screen tearing).

Why go through all these steps? Why not just do step 2, just simply locking my framerate to 49hz and be done with it? Because 49hz is not a factor of 60, and so it'll be out of sync and look like shit (not smooth at all). The next factor of 60 is 30, but 30fps feels and looks like crap (I start noticing severe choppiness at anything less than 48 fps -- it seems weird to me that the cutoff is so abrupt, but whatever).

Doing it this way, I literally cannot tell the difference between 60 and 49 fps* because it's in sync with my LCD'd refresh rate. 49!!! That sounds crazy, right?! But it's true.

* Only tested so far in games with decent motion blur (like unreal engine 4+ games) -- perhaps a reshade shader can provide a decent enough motion blur in games that don't have one. If not, I can write one.

This gives a "virtual" overclock boost of (1.0 - 49/60) 18.33% on BOTH my CPU and GPU at the cost of increased latency ((1/49 - 1/60) * 1000) 3.7415ms. This is a MULTIPLICATIVE boost with normal cpu and gpu overclocking. Well worth it IMO. Do you really think you'll notice an additional 3.75ms of input lag? I don't. Additionally, as a knock-on effect, this will actually produce smoother gameplay by reducing micro stutters and even larger stutters from texture loading/streaming and similar stuff.

I'm curious to know if other people have different subjective cut-off points for what begins to look/feel choppy. I suspect not because all humans are virtually identical biologically (we're all susceptible to the same optical illusions right? That tells me that we're all using the same optical optimizations/hacks/shortcuts to experience motion from a series of still frames), but maybe... Who knows?

That issue doesn't really have anything to do with CRU.

You can try forcing 320x240 internal resolution with Special K, then it would be fullscreen

Hello, one thing I do not understand, what exactly is back porch, and why is the value different on my monitor?

When I reset my monitor I get the values back porch 3 lines, but native PC changes this value to 54 lines, all other values are the same.

I actually mostly just change the refresh rate to a smooth 60, you can argue about that now, but that has nothing to do with back porch.

The problem I have, whenever I change some things, I feel like I get headaches and migraines quickly, because I'm very prone to them, even if I don't feel like the monitor is different because of my settings.
I attach my settings, maybe someone has time and desire to look over whether I do something wrong.

It's just padding basically. It doesn't affect the image. CRU is using the CVT-RB standard in that case. The monitor has the vertical front porch and back porch swapped, but that only affects the timing of the sync pulse.

Hi all, I just made an account here to ask a question because I simply cannot find a solution anywhere and this is probably my only hope:

I have a weird, offbrand Electriq monitor that is 4k 144hz when using 2 1.4DP cables (no hdmi 2.1). With one cable it runs at 120hz and I can OC to 130hz no problem. But with 2 I think I can go beyond 144hz but it might be some software/hardware capped (in the monitor bios i need to toggle 144hz mode ON). It's obviously tiling the picture over the two halves of the screen via each cable to achieve 144hz. How can I try OC this with CRU? Is it possible?

Any help is appreciated!

Are there any tips for making my LCD downlclock to 48hz without it becoming blurry?

I can go down to 49hz no prob (actually, 48.9 is fine but 48.8 gets blurry and choppy) -- still nice and sharp. And I can go all the way up to 75hz and it's still nice and sharp.

But 48hz is blurry as hell and it starts getting choppy.

If I manually increase the backporch, it looks a bit better -- but nowhere near as good as 49 or anything else. Does it have something to do with the pixel clock?

AND...

What happens when you just try to OC it to 145hz?

There's no reason it should be blurry. That sounds like a monitor limitation.

Each half should be listed as a separate monitor in CRU. You would have to add 1920x1440 @ whatever refresh rate to both halves.

Oh well... I guess I'll just use 23.977 * 3 = 71.931hz for watching NTSC tv shows then.
