Re: Sallos?
Turn off shadows, use the lowest graphics settings. Use a low resolution also - this makes a huge difference. I use 800x600 desktop resolution when using Sallos. Also, open task manager and go to processes, right click "Sallos" and set priority to low or below normal. Make sure your using Sallos and not PlayUO too, since PlayUO disconnects after a few seconds. If your still disconnecting, make sure your firewall isn't blocking the program.
On Sallos.net download Microsoft .NET Framework 2.0 and Microsoft DirectX 9.0c if you don't have it all already. Worst comes to worst, upgrade your RAM. RAM is cheap and easy to install, you can buy decent ones for $60-100 US.
If it becomes playable, make sure to restart Sallos every hour or so since it consumes more RAM the longer it's open.
And if you need a good macro template to get started, the file to my macros is in my sig.
