Garrys Mod – Wie man hochauflösende Screenshots macht

Einführung

If you like to make GMod posters, you may have run into a desire to take higher-res screenshots than your monitor supports. Zum Beispiel, I’m stuck with a 1080p monitor, which can mean that small details in posters can be difficult to see sometimes.

The common advice you hear for this is to use the „poster“ Befehl. Zum Beispiel, „poster 2“ will create a screenshot with 2x the horizontal and vertical resolution (z.B. 1920×1080 -> 3840×2160). Bedauerlicherweise, this method can cause some nasty visual artifacts. To demonstrate, hier ist a comparison, with the same basic shot taken with multiple settings. Wie Sie sehen können, the second pic looks awful – the water reflection is totally broken, and there’s a clear seam where the image was stitched together.

Jedoch, the album also contains a third image – a proper 4k screenshot with none of these artifacts, verwenden „supersampling“. What exactly is this, and how can it help us?

Supersampling

Supersampling involves rendering the game at a higher resolution than your monitor normally allows, and then scaling it down afterward. It’s normally used as an anti-aliasing strategy (the additional pixels allow a smoother image to be created), Aber you can also take advantage of that higher resolution for your screenshots.

It turns out that graphics drivers have built-in ways to enable supersampling. Here are instructions on how to enable it for both Nvidia and AMD cards. If you already know this stuff, feel free to skip to the „What to do with supersampling“ Abschnitt.

Enabling supersampling with Nvidia

Nvidia’s supersampling feature is called Dynamic Super Resolution, or DSR.

1. Offen Nvidia-Systemsteuerung. You should be able to find it in the Start menu.
2. Navigieren Sie zu 3D -Einstellungen verwalten Speisekarte, underneath the „3D Settings“ header on the left.
3. Make sure you’re in the Global Settings Tab, rather than the Program Settings tab. (Don’t worry that the setting is global – this will just enable additional resolution options in your games, it shouldn’t affect anything by default.)
4. Scrollen Sie nach unten zum DSR – Faktoren setting and select it.
5. Underneath the Legacy scaling Abschnitt, check off the resolutions you wish to enable, und dann klicken OK. (Notiz, this is based on the pixel count and not the scale factor, so 4.00x is actually just double width and height.)
6. Endlich, klicken Anwenden at the bottom to actually save your changes.

Und schon sind Sie fertig! You can proceed to the „What to do with supersampling“ Abschnitt.

Enabling supersampling with AMD

AAMD’s supersampling feature is called Virtual Super Resolution, or VSR.

Notiz: I don’t have an AMD card myself, so these instructions come straight from this article. If someone wants to confirm that these steps are correct, that’d be much appreciated.

1. Offen AMD Radeon Software.
2. Click the gear icon in the upper right, und wählen Sie die aus Anzeige Tab.
3. Turn the Virtual Super Resolution setting on. This will enable all supported supersampling resolution options in-game.

What to do with supersampling

So now you have supersampling enabled, but how do you use it? Es ist einfach: once you’re in-game, just go to Optionen > Video and check out the resolution settings. If you’ve done everything right, you should see new option(S) that let you use higher than native resolution.

Once you’re using the higher resolution, all you need to do is use the poster 1 Befehl (nicht poster 2, Nur 1), or take a screenshot in some other way, and bam – you’ve got yourself a pic with as high a res as possible, and none of those ugly stitching artifacts!

There are a couple caveats worth mentioning, Jedoch:

• GMod doesn’t have any UI scaling, so the UI will only show up at half scale and make things very difficult to use. Ich würde es empfehlen only switching for the moment you’re ready to take the final shot. Der „mat_setvideomode“ Befehl (described below) can help a little with this.
• Das does not work properly with borderless window. You’ll only be able to see the top left corner of the screen. You need to use proper fullscreen mode if you want to see the whole game (Obwohl die „poster“ command will still work fine regardless).

Shortcut command to change resolution

mat_setvideomode is a console command that simply changes the resolution and display mode settings. Es ist nicht streng notwendig, but it’s a very nice convenience, since you can bind it to a key and it skips having to navigate the menus (which can be difficult while you’re set to a higher res).

The syntax is:

mat_setvideomode [w] [H] [Modus]

Wo w is width, H is height, Und Modus is either 0 for fullscreen, 1 for windowed, oder 2 for borderless windowed.

Als Beispiel, I currently have one key bound to mat_setvideomode 3840 2160 0, to set 4k resolution and fullscreen mode; and another key bound to mat_setvideomode 1920 1080 2, to return to normal 1080p resolution and borderless windowed mode.

Denken Sie daran, Jedoch, that this doesn’t let you skip turning on supersampling in your graphics driver settings. If you give the command an invalid resolution (anything that wouldn’t normally appear in the settings menu) it will just default to 640×480 stattdessen. So it really is just a convenience, nichts mehr.
