When we are playing some 3D games, the game may encounter problems such as picture jam, or even crash because the performance of our computer hardware cannot keep up with the demands of game. Of course, there are a lot of graphics card optimization software, such as Rivatuner, Nvmax, Rage3D, etc., but most of them cannot optimize all the graphics adapters in the market. More importantly, the traditional optimizer perform optimizations based on the architecture of graphics card itself, which at best makes the graphics card better play its own performance.

Take Off - The Flight Simulator is a realistic, first-person flight simulating game more than a real flight simulator (in fact, it's actually a game ported from mobile platform to PC). At this point, we can directly predict from two aspects before starting to play it: 1) its official website has the word "mobile" in its homepage address; 2) the size of its game content after compression is just bigger than 500 MB. It's developed by Jujubee S.A. and published by astragon Entertainment from Germany in 2017.

In order to reproduce Vagrant Story's game levels (rooms, weapons, props, enemies, etc.), for a long time I searched everywhere and looked for any tool that could extract sound and graphics files from this my only favorite PSOne video game. The Vagrant Story Tools, which seems to be the most effective and perfect solution now, may be just a joke and scam - it never works (and its developers do not respond to any feedback). Finally, only PSound and its sister software PSicture (the later requires PSi_VARY, but I couldn't make it work) can help us a little.
