Da parte da AMD já me responderam aos mails e da Clevo também. Continuam a bater na tecla que o suporte deve ser dado por parte do manufacture ou seja a Clevo.
Por parte da Clevo chegam a referir que devo pedir assistência ao reseller/vendor para ele me dar as bios e drivers mais recentes. Ora o reseller neste caso seriam as nossas lojas portuguesas. Não me parece que elas tenham algo que a Clevo não tenha...
Aqui vão as duas respostas que tive por parte da AMD:
Quando questionados sobre a falta de suporte no Windows 8 e sobre os problemas de desempenho da 7970 no windows 7 provavelmente ao enduro:
I understand that you are having some issues with your laptop running a Radeon HD 7970 M chipset. It appears as though you have tried to find alternate drivers however your issue persists.
If I have missed any critical information please let me know as my suggestions may change.
All laptop manufacturers provide their own optimized and proprietary drivers for their machines because the GPUs in those machine have been altered and optimized for those specific systems.
This means you have no choice but to use the Clevo drivers as they are the only drivers offered for your system. If those drivers or equipment are not functioning as expected you are advised to contact Clevo as they are the only source of support for their products, we simply have no resources or knowledge of the products beyond the basic specs of the chipset.
As for finding windows 8 drivers you may be waiting a while for those. Besides the fact the operating system has not actually been released, the drivers like all drivers will have to come from Clevo. Considering most laptop makers are more interested in selling new windows 8 machines when they are available rather than spend resources writing drivers for older hardware and that the OS itself has a little over 2 months still to be released I would expect to see windows 8 drivers for that machine sometime near the new year or possibly never. They will tell you the machine shipped with Windows 7 and thus they may not bother supporting windows 8, this is unfortunately sometimes the case. I would recommend waiting for drivers to be released before investing in an OS upgrade for that machine.
The above information holds true with virtually all laptops whether they be Apple, HP, Dell or Clevo. Laptop drivers must come from the laptop manufacturer.
Depois desta resposta insisti novamente indicando vários relatos pela internet fora onde todos apontavam para falhas no enduro. Questionei-os ainda se os driver reference deles alguma vez iriam suportar a AMD 7970M dos Clevo. A resposta foi esta:
Unfortunately I do not know any information regarding future driver releases. From my position here I am not privy to information any sooner than the general public.
We appreciate the feedback and concern coming from yourself and other users. I have forwarded this information to our driver team for their knowledge. You can also send this information or anything else to the following link and this will go directly to the teams responsible for getting such drivers released.

Pela parte da Clevo, estavam a ser mais discretos nos comentários mas o último email alargaram-se mais um bocado e pediram mais detalhes sobre os problemas.
Resposta ao primeiro email onde alerto para os problemas de desempenho da 7970 provavelmente causados por problemas no Enduro e onde questiono o futuro suporte do Clevo P150EM no windows 8 (uma vez que a AMD alertou para o facto de poder falhar o suporte).
For this molel to use WIN8 BIOS and driver are not ready at the moment. you can check with vender where you bought form, when the BIOS and driver ready they update to you.
Ignoraram por completo todas as referências aos Windows 7 e aos problemas do Enduro. Tornei a insistir novamente com outro email onde ha semelhança do que havia feito na segunda resposta da AMD, indico vários casos concretos e links para fóruns. A resposta foi a seguinte:
For Win8 BIOS and driver we are studying test at the moment. when it ready we will update to our distributer, if you need any BIOS and driver you can ask from you bought the lapotp vender, they will update to you.
And the game we have testing many days the point is stay at 60fsp we didn't find it stay at 40-20fps on my side.
If you can update clearly information to us we can duplicate to do to check on my side.
1. Laptop serial number
2. BIOS version
3. EC
4. OS
5. CPU
6. VGA card and driver version?
7. Test with which game ? ( please provide video you test the result?)
8. How to setup VGA performance and power mangement?
Could you please check on your systems the VGA performance setting doe sit correct?
Aparentemente está para sair nova bios com "suporte" para o windows 8... ou foi só para me despachar...
Vou ver se faço uns testes de forma a preencher os pontos que a Clevo pediu de forma a fornecer "clear information". Não tenho é muitos jogos recentes, se alguem estiver interessado pode fazer o mesmo e colocar aqui eu depois anexo ao meu email. Assim podemos enviar feedback variado.
Se alguem estiver interessado que me informe que eu fico a aguardar até responderem.
