[Lua Version - how to hide Game DOS Window, or remove it completely?]

I have the Lua Version (Indie), and compiled games show an unnecessary DOS Window which the user really doesn't want to read. How to disable it? It gives a bad impression.

OK, sure, is there a guide how to do it? Is this in Lua script?

I have a question regarding ATI GPU with following system specs and would be grateful if someone with the same specs can share info about performance.

 

Toshiba Satellite

Windows 8.1 64bit

AMD quad core - A6-5200 ~ 2.0 GHz

RAM 4 B

GPU AMD Radeon HD 8400

 

I get with average level only around 12-19 Fames/second, which is strange. Also, in comparison to AAA games overall it's all very sluggish.
