GAMEPLAN

This is normal. The speed will vary depending on how many seeders / leechers are connected to your PC at that moment and at what speed they are uploading the file to you. Your download speed will always start slow at the beginning and it will stabilize in 30 minutes most of the time. But be sure to pick a file with the best seed / leech ratio !

If you’re using the internet while you download, the download speed will drop a lot, so I recommend you to leave the PC on while you’re asleep to get these done quickly.

============= HOW TO SPEED IT UP ? ============

However, there are a few things that can speed things up. Go to http://www.speedtest.net and test your connection speed out. Then, choose the settings that correspond to your results.

Also, allow an UNLIMITED speed for uploading. Don’t set limits. In this world, you get what you give (and that’s real). This will NOT affect your download speed EVER.

What software are you using to download the games ? If you’re using uTorrent, I suggest reading the following guides:

If you ran out of options, then get a faster connection. Ah, and make sure your internet is WIRED when the thing is downloading big files.

============ RECOMMENDATIONS ===============

Oh and remember, downloading games is illeg… ah, the hell with it ! >:D
