After installing Windows 10 Technical Preview (a clean install) pretty much 99% of my games stopped working. Most of these I got on Steam, so when I try to play one, it starts the first-time setup, where it tries to install DirectX and then it just returns to desktop. If I try again, it just does the same, but if it's one of the few games which don't install it when running them the first time (i.e., Binding of Isaac), then it has no problems.
After that, I tried to play a couple of relatively new games I got from GoG, but they gave me error messages when trying to install DirectX. They still install, but if I try to play them they don't run because they can't find DirectX-related dlls in the computer.
According to Dxdiag, though, DirectX 11 is installed. Reading forums, it seems to me that most people can play games with no problem with the Tech Preview, but some can't because Windows 10 doesn't recognize their graphic cards, and they have to switch to integrated graphics. I can't do this, as my motherboard doesn't have them, but at least when checking system information it seems that the OS recognizes the card (a Radeon Hd 4870, not exactly cutting edge stuff...), so not sure if it's the same, though it might be, as I tried installing the latest drivers for Windows 7/8 and couldn't. Has anybody had similar problems? And did anyone manage to solve them, and how?

Hi,
I would suggest you to provide the feedback in the feedback app so that it will be implemented in the future Builds.

Hope this helps. Let us know if you have any other issues with Windows in future.
To get your games to play on windows 10.Install 3d builder app for win 10.Worked for me.Good Luck
Another nice example.....
Points 2, 3 and 4 are irrelevant:
2, It can be nVidia or AMD or Intel graphics card. It can be new or old. It doesn't matter when it is bad piece.
3, Same as point 2 - some card are can pass tests in manufacture but in the real usage they can fail.
4, If it is bad graphics core or graphics RAM then it doesn't matter too which cable you use.
Point 1 is good one. This issue should be in more games. The other games are less graphic demanding?
Because you can try for example Heaven benchmark: https://unigine.com/en/products/benchmarks/heaven or the other demanding types of applications on you hardware.
Watch it and if it will be doing same thing then it is HW related.
Good idea, i will download/try a benchmark! Thanks and your English is great! :)
Yes, Windows supports more than one version of DirectX. For example Windows 10 supports DirectX 9 to DirectX 12.
But it is not on Microsoft developers which DirectX version your games will use. It is on game developers. Games had/have two executable files - one for DirectX 9 and one for DirectX 10 (or 10 / 11 or 9 / 11) or option in game setting for switching DirectX version.
It was because of HW issues where new DirectX was much more demanding on HW power then older one. But the new one looks better.
Another problem is when you don't have for example DirectX 11 support on you graphics card but games want it then it is SW simulated and it is really slow compared to HW acceleration.
So yeah, you can switch between DirectX versions in games, however they have to support this feature. But there is no point in doing this if your game is not lagging or you want more frames per second and lower you graphic quality.
Sorry for bad English.
