PNGGauntlet 3.1.2
Reduce the size of PNG images without any loss in quality

PNGGauntlet can compress PNG images to make them more efficient, so reducing file size while maintaining the same image quality. This can be particularly good news on websites, where it makes pages faster to load and reduces your bandwidth requirements, but this kind of shrinkage has advantages anywhere that PNG files are used.

The program works by combining three open-source image optimisation tools - PNGOUT, OptiPNG and DeflOpt - to deliver the best possible compression.

But while these core tools are fairly complex, you don't have to understand any of the low-level technicalities to use PNGGauntlet. Just drag and drop your target images onto the program, choose an Output folder, click "Optimize!" and watch as your images are tweaked.

Does it work? We tested the program with six large PNG-format logos. These were found online, so we'd expect them to be reasonably compressed already, but PNGGauntlet still achieved impressive results. One file was reduced from 71.63KB to 39.44KB in size (a 44% cut); others were cut by 24%, 20% and 7%, and even the best compressed two were still reduced in size by a few bytes.

That's not bad at all. If you need more control, though, clicking Tools > Options does give you access to the various PNGOUT, OptiPNG and DeflOpt settings (although you will need a good understanding of low-level PNG structures to get the most from them).

Verdict:

PNGGauntlet provides a super-easy way to optimise your PNG images, and it can deliver some very impressive compression results. Go grab a copy immediately.

Unreal Engine 4.8

Free Full Commercial Software

Unreal Engine is Epic Games' game engine, a powerful suite of tools for developing anything from basic 2D games to professional RPGs, first person shooters and whatever else you like.

Wide standards support - DirectX, OpenGL, JavaScript/ WebGL - means your projects can be targeted to almost any platform: consoles, iOS, Android, Windows, OS X, Linux, HTML5 browsers and more.

There's a vast amount to learn, of course, and that's even before you start building your game. But there's plenty of documentation, tutorials, demos and sample projects to point you in the right direction.

The package is now entirely free, too - no annoying limitations, nag screens or anything else. Epic now only requires that you pay a 5% royalty after the first $3,000 of revenue per product per quarter. And even then, you "pay no royalty for film projects, contracting and consulting projects such as architecture, simulation and visualization."

8.48 brings:
    - Optimized grass rendering and procedural foliage system preview
    - Plugins available in Marketplace
    - Improved accuracy for motion blur
    - New Tone Mapper
    - Support for all the latest VR hardware including Oculus Rift, Samsung Gear VR, Steam VR and HTC Vive, Leap Motion, and Sony's Project Morpheus for PlayStation 4
