Played it fine the other day deleting worlds to make room for the update. Updated while I was out grocery shopping. Got all excited to see 1.1.... Click Terraria..... Game screen loads........ Terraria: Error System.OutOfMemoryException: Insufficient memory to continue the execution of the program. at Microsoft.Xna.Framework.Graphics.Texture2D.CreateTexture(GraphicsDevice graphicsDevice, Int32 width, Int32 height, Boolean mipMap, UInt32 usage, _D3DPOOL pool, SurfaceFormat format) at Microsoft.Xna.Framework.Graphics.RenderTarget2D.CreateRenderTarget(GraphicsDevice graphicsDevice, Int32 width, Int32 height, Boolean mipMap, SurfaceFormat preferredFormat, DepthFormat preferredDepthFormat, Int32 preferredMultiSampleCount, RenderTargetUsage usage) at Microsoft.Xna.Framework.Graphics.RenderTarget2D..ctor(GraphicsDevice graphicsDevice, Int32 width, Int32 height, Boolean mipMap, SurfaceFormat preferredFormat, DepthFormat preferredDepthFormat) at Terraria.Main.InitTargets() at Terraria.Main.Draw(GameTime gameTime) at Microsoft.Xna.Framework.Game.DrawFrame() at Microsoft.Xna.Framework.Game.Tick() at Microsoft.Xna.Framework.Game.HostIdle(Object sender, EventArgs e) at Microsoft.Xna.Framework.GameHost.OnIdle() at Microsoft.Xna.Framework.WindowsGameHost.RunOneFrame() at Microsoft.Xna.Framework.WindowsGameHost.ApplicationIdle(Object sender, EventArgs e) at System.Windows.Forms.Application.ThreadContext.System.Windows.Forms.UnsafeNativeMethods.IMsoComponent.FDoIdle(Int32 grfidlef) at System.Windows.Forms.Application.ComponentManager.System.Windows.Forms.UnsafeNativeMethods.IMsoComponentManager.FPushMessageLoop(IntPtr dwComponentID, Int32 reason, Int32 pvLoopData) at System.Windows.Forms.Application.ThreadContext.RunMessageLoopInner(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.ThreadContext.RunMessageLoop(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.Run(Form mainForm) at Microsoft.Xna.Framework.WindowsGameHost.Run() at Microsoft.Xna.Framework.Game.RunGame(Boolean useBlockingRun) at Terraria.Program.Main(String args) And here I was worried the new lighting would kill my FPS like .05 did. Now I can't even play at all, sweet. So far I've tried rebooting.. but still get the error. I am not happy at all. Update: Well, it seems for most of us the new lighting system is the issue. What has worked for most of us is replacing the config.dat file located in My Documents > My Games > Terraria with a new one. This zipped Config.dat is clean, safe and 800x600 Resolution with Retro lighting. I think paralax is at 100 and frameskip is off. I personally play on a netbook so the resolution is fine for me. It still crashes if I try to use the new lighting system. Retro and Trippy work for me. It should load for you if it didn't before. If it still crashes for with this config.dat I'm not sure what to tell you. The changing background still cause major framerate drop, nothing we can do about that sadly.
