PGT: GFX, Launcher & Optimizer

Review by eFreeware

Most graphics tools for Android games try to do a bit of everything. PGT does one narrow job: it sits in front of a specific set of FPS mobile games and rewrites their visual settings, from resolution and shadows through to frame-rate caps. That focus is the most distinctive thing about it, and it is also the clearest signal of who it is for. If the game you play is not one of the supported titles, nothing here applies to you.

The app comes from Trilokia Inc. and sits in the Libraries & Demo category rather than Games, which fits its role as a utility that runs alongside another app. It has been installed more than 10 million times and holds a 4.4 average across 188,577 ratings, and it dates back to May 2018 with an update in October 2026. It is free to install and supported by ads, and there are no in-app purchases to consider.

In practice, PGT suits players on mid-range or older phones who feel their game is either choppy or bland and want more control than the in-game menu gives them. It also appeals to anyone who enjoys tinkering with settings and comparing results. It is not a general performance booster for your whole phone.

What the launcher actually changes

The core of PGT is a set of graphics presets that you apply before launching your game. Two named options stand out: Potato graphics, which strips the visuals back as far as the app allows, and Simple shaders, which sits at the other end of that scale without going all the way to maximum. These give you a fast way to switch between a smoother, plainer look and something richer, without digging through menus inside the game itself.

Beyond presets, the app exposes a wide spread of individual settings. You can change the resolution the game renders at, apply HDR and UHD graphics on low-end devices, raise the frame-rate ceiling to as much as 120 FPS, adjust shadows, switch on anti-aliasing and set audio quality to Ultra. The developer groups these into basic, miscellaneous, advanced and experimental categories, which suggests a sensible split between safe everyday tweaks and options that carry more risk.

That last group is the one I would treat with care. Experimental settings are exactly what the name implies, and changing how a game renders can produce results the developer did not intend. The upside is real, though: raising resolution and frame caps on hardware that normally cannot manage them is the whole point of a tool like this.

The supporting pieces around the presets

PGT is not just a settings panel. The developer lists support for every major Android release from 4.3 to 17 and beyond, which covers a very wide spread of devices, and the recent update narrows its stated compatibility to Android 7 through 17 while adding a Flash variant and full support for version 4.6.x of the game it targets. Those two statements sit slightly awkwardly together, but the intent is clear enough: broad device support with the newest game builds handled.

It also covers all the regional releases of the game, listing Global, CN, LITE, KR, VN, TW and BETA. That matters if you play a localized build. There is a Help & FAQ section built in with tips, which is a reasonable place to start before touching anything advanced.

The app was featured on the XDA Portal, according to the developer, which is the kind of recognition that tends to matter to people who already read about Android tweaking. It is not a reason on its own to install something, but it does suggest the tool has been looked at by people who know the space.

What it asks of your phone

PGT requests three permissions, and each has a stated purpose. Storage access is used to apply and back up graphics settings, internet access loads settings from the developer's server, and permission to kill background apps is used for memory boosting. None of these are unusual for a utility of this type.

The app is free and carries ads. There are no in-app purchases. You will need a supported version of the game installed for any of this to have an effect, and the developer asks that you read and accept the privacy policy and terms of service before using it.

The practical requirement is simply that your device runs one of the supported game builds and an Android version the app accepts. If either of those is missing, the settings have nothing to act on.

Getting sensible results from it

My advice would be to start with the presets rather than the individual sliders. Potato graphics and Simple shaders give you two clear reference points, and once you know how each feels in play, the advanced options make more sense. Changing resolution, shadows, anti-aliasing and the frame cap all at once makes it hard to tell which adjustment helped and which hurt.

The frame-rate setting deserves particular restraint. Pushing toward 120 FPS on hardware that struggles will not create smoothness out of nothing. The app can request those settings; whether your phone can sustain them is a separate question. Move up in steps and stop when the experience stops improving.

Before you change anything, it is worth keeping a copy of your original settings. That way an experimental combination that looks wrong or runs badly is a quick restore rather than a reinstall. The built-in Help & FAQ is the other resource to check first, since it exists precisely to save you from guessing.

A focused tool for a specific kind of player

PGT is a narrow utility that does its job well for the audience it was built for. The regional build coverage and the wide Android support range make it accommodating.

The trade-offs are straightforward. It is tied to particular games and it shows ads. None of that undermines the core offer, but it does mean the app is only useful to you if you actually play one of the supported titles.

If you do, and your phone leaves you choosing between a smooth game and a good-looking one, PGT is a reasonable thing to install. This app concentrates on graphics settings and launcher customization for Android.
