RamGuard

Have you ever had players complain about crashes or low frame rates only to discover that they were using your 250+ ModPack with 2 GB of RAM? RamGuard detects this immediately upon launch. It saves you from repeatedly responding to troubleshooting questions by reading the memory allotted before the main menu loads and alerting the player if additional memory is needed.

Highlights
