Speed up your internet connection. Maybe. TCP Optimizer is a free tool which tweaks various Windows settings to try and speed up your network connection.

The program is compact, portable, and you don't need to know anything about TCP/IP to use it.

Basic operations are simple. Launch the program as an administrator, choose a network adapter, set your internet connection speed, choose "Optimal" and click Apply.

TCP Optimizer then displays your new settings. This really is cryptic, but ignore them, check the Backup option, click OK and restart your PC when asked.

Don't expect too much. Unless your previous settings were totally messed up, you're not going to find your download speed has doubled. When we tried it on a test laptop, download performance was exactly the same, but uploading was consistently around 10% faster, and even that was better than we expected.

When you're trying to assess results, keep in mind that simple measures like upload/ download speeds don't tell you everything about your network performance. TCP Optimizer may also help improve speeds across a busy network, for instance, or when you have multiple connections open, but websites can't tell you about that.

If you don't see any real change, it's possible to view and manually tweak various Windows network settings (although you'll need some networking expertise to figure them out).

If there's still no improvement, or your connection seems slower (yes, that's possible), then click File > Restore Backup Settings, choose a backup file (FirstBackup.spg was created on the program's first launch, manual backups are named with the date and time they were created), apply the results and reboot to get everything back the way it was.


Windows generally does a good job of optimizing your network settings, and in our experience third-party optimizers make little difference. TCP Optimizer does a better job than most, though, and if the tweaks don't work out then it's easy to restore your original settings.

Unreal Engine 4.15.1

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."
