Intel Integrated Graphics is simply too weak for shaders. The game will work like before (and maybe even better) if you disable shaders but it's not optimized for shaders because it's weak
Nope, not true at all, sorry. Intel chips are built for shaders otherwise they wouldn't pass shader tests or support anywhere from GLSL 2.0 - 4.0 (depending on the chip). Most of the latest chips can run up to version 4.0 shaders fast. Any laptops running Ivy Bridge will be especially fast (the Intel HD3000 actually runs faster than most other laptop graphics cards, from NVIDIA and co.). The 3000 can run Skyrim anywhere from medium to high (depending on processor and RAM), for example.
The thing that will kill the performance for old Intel cards will be the extra draw calls for any antialiasing or shadows. Although, notably, most Intel cards can run Skyrim (I'm using this as an example because it has quite a lot of shader usage) on low with low resolution shadows and textures.
The issue is not that Intel chips can't support Blockland. It's that Torque's rendering engine was not built for this sort of thing, so it will probably take a fair bit of tweaking for Badspot and kompressor to optimize it further to the point where Intel chips are supported. Or they might not even bother, which would be a disappointing result seeing as a large majority of users here use Laptops with Intel graphics chips.
