To Bryan : If you put it to Software renderer, it will work, BUT you won't have the AA(FSAA) neither an 'higher' graphic(texture in the background and character) quality. Hardware renderer use your graphic card and use the effect we like, like the AA and I think it also use AF but I'm not sure about that.
So to come back to your problem,I'll suggest you to :
- Upgrade the Directx if it can help...
- If you downloaded the 1.31 version of the launcher, check if the expert mode isn't activated(it helped me),
- Also you may want to download your latest driver for your graphic card.
- You can put a more detailled specification of your computer if you want more people to help you...
- Then check if you have selected the 4:3 stretch, maybe u have a 4:3 screen and if so u should disable the 4:3 stretch if it isn't already off.
If that doesn't work then ask magicxts if he can help you with that, after all he's the one who created that launcher
