**System Information**
Windows 7
CPU: Quad core 3.1 ghz
GPU: Nvidia GTX970 super clocked 4GB
**Blender Version**
Broken: (2.73 RC Hash: 273fa0a and 2.72b )
Worked: (not sure only have those two)
**Short description of error**
When rendering on gpu with an environment texture for color in the world settings i get the error message: "CUDA error: Launch failed in cuMemcpy2D(¶m)" this only happens with an environment texture :\ (using an hdr)
**Exact steps for others to reproduce the error**
1. using a GPU (mine is a gtx970) enable rendering with that gpu
2. in the world panel change the color type to "environment texture"
3. load in a .hdr image
4. render. error coming up for me again is: "CUDA error: Launch failed in cuMemcpy2D(¶m)"
