Hi, Ati brings his first "fixed" Opengl drivers for never Ati Cards out.
It on my ati 5870 many Lags that i had on winxp and Win7 under opengl.
I think the overall perfomance is better to.

AMD Catalyst™ Preview Driver Features:
Full support for the new OpenGL 4.2 specification. High-lights include:
City of Heroes: Resolves image corruption and random hangs found when playing City of Heroes
Enhanced support for generic read-write memory and high performance atomics in shaders (EXT_shader_image_load_store and ARB_shader_atomic_counters extensions), allowing advanced graphics algorithms to be implemented.
Increased flexibility in how texture memory is allocated and managed (ARB_compressed_texture_pixel_storage and EXT_texture_storage extensions).
Improved control and access to geometry instancing for improved performance (ARB_transform_feedback_instanced and ARB_base_instance).
Improvements to the OpenGL Shading Language (GLSL).
Added control over GPU optimizations related to depth testing (AMD_conservative_depth).
Improved guarantees about the alignment of mapped GPU memory (ARB_map_buffer_alignment).
