If nothing is shown, it's most likely that Blender does not detect your GPU as being able to handle OSD requirements. Given yours, it’s likely a driver issue, so first you should try if not yet done is to update them to latest version.

If this still fails, please attach here the report generated by Help -> System Info.

Please read the documentation here:

Currently GLSL Compute evaluator is disabled for AMD hardware. This is because of issue in the OpenSubdiv itself which is being worked on but didn't quite managed to be solved before Blender release.

@Aaron Carlisle (Blendify) only GLSL OSD is disabled on AMD GPUs, not whole OSD (CPU & OMP options shall remain available, provided drawing capacities are met)!

Sorry for the misunderstanding read it too quickly

Since it's an old card the latest drivers are Catalyst 13.9 which are installed.

Thanks, can confirm your driver/GPU does not support ARB_gpu_shader5, which is required to draw OSD (see also T45717 for details).
