Hi, I've just upgraded to Windows 8.1 in my laptop and now I can't launch catalyst app (it says there aren't any configurations to apply using CCC) and games using OpenGL lag like hell. I've been searching and reading and apparently the problem is very common and the solution is installing latest catalyst beta (13 and 14 versions, which are the ones compatible with windows 8.1).

The problem is that those drivers are only compatible on HD 5000 version and higher so I guess they won't work on my ATI Mobility Radeon HD 4300. What can I do to make it work? 

Thanks.

The 4xxx series graphics are not compatible with Windows 8.1. They do not meet Micro$ofts requirements. Go back to Windows 7.

I ran the 8.1 preview (the 90 day trial you can/could download from the MS site) just to see what they 'fixed' on 8.1 vs. 8, and did so just fine with my crossfired 4890's.  Played games just fine.  That trial is long gone now so I can't access the drive/OS to tell ya what I used, but I'd guess/assume I either found drivers via auto-detect on the AMD site, or if that failed (or I just didn't do it) I probaly used my 13.9 drivers (sitting on archive drive here) for win7.

I think you should read the manual. As far as i know, It is compatible with Windows 8.1.

No I am familiar with the requirements. You cannot make the 4xxx series cards fully compatible with win 8.1. Win 8 would allow decent performance even though the 4xxx do not fully meet the WDM requirements. Windows 8.1 is not as tolerant.  Using a WDM 1 card will cause dependant program issues.

Wiki:

WDDM 1.1[edit]

Windows 7 supports major additions to WDDM known as WDDM 1.1; the details of this new version were unveiled at WinHEC 2008. New features include:[9]

Hardware acceleration of GDI and Direct2D/DirectWrite operations helps reduce memory footprint in Windows 7, because DWM compositing engine no longer needs to keep a system memory copy of all surfaces used by GDI/GDI+, as in Windows Vista.[20][21][22]

DXGI 1.1, Direct3D 11, Direct2D, and DirectWrite were made available with Windows Vista Platform Update; however GDI/GDI+ in Vista continues to rely on software rendering[23] and the Desktop Window Manager continues to use Direct3D 9Ex.[24]

WDDM 1.1 drivers are backward compatible with WDDM 1.0 specification; both 1.0 and 1.1 drivers can be used in Windows Vista with or without the Platform Update.[9]

WDDM 1.2[edit]

Windows 8 includes WDDM 1.2[25][26] and DXGI 1.2.[26][27] New features were first previewed at the Windows BUILD 2011 conference and include performance improvements as well as support for stereoscopic 3D rendering and video playback.

Other major features include preemptive multitasking with finer granularity (DMA buffer, primitive, triangle, pixel, or instruction-level),[28] reduced memory footprint, improved resource sharing, and faster timeout detection and recovery. 16-bit color surface formats (565, 5551, 4444) are mandatory in Windows 8, and Direct3D 11 Video supports YUV 4:4:4/4:2:2/4:2:0/4:1:1 video formats with 8, 10, and 16-bit precision, as well as 4 and 8-bit palettized formats.[29]

WDDM 1.0/1.1 only allows rudimentary task scheduling using "batch queue" granularity; improvements to multitasking, as well as fast context switching and support for virtual memory, were initially expected in WDDM 2.0 and 2.1, announced at WinHEC 2006.[30][31][32]

WDDM 1.3[edit]

Windows 8.1 includes WDDM1.3[33] and DXGI 1.3.[34] New additions according to preliminary documentation are trim DXGI adapter memory usage, multi-plane overlays, overlapping swap chains and swap chain scaling, select backbuffer subregion for swap chain and lower-latency swap chain presentation. Driver feature additions include wireless displays (Miracast), YUV format ranges, cross-adapter resources and GPU engine enumeration capabilities.
