Sometimes, when I launch my game in LibGDX (the game doesn't require much power) the rendering is very laggy, but most of the time, when I run it the game runs smooth perfectly.
I would understand this if it would be laggy all the time, but it's laggy only in about 10% of the times when I run it. When I close it and run it again, it runs perfectly. Why is this happening?
I use Eclipse for launching and it runs as a desktop app.
I had the same problem. Try running it alone without Eclipse and it should work.
