So I have a Dell Latitude E6540, with these specs :
- Processeur Intel® Core™ i7-4800MQ
- Windows 7 Pro 64 bits
- DDR3L 8 Go 1600 MHz
- Hybrid SSD 500 Go (5 400 tr/min) with 8 Go of flash memory
- Carte graphique AMD Radeon HD 8690M GDDR5 de 2 Go
- Integrated GPU Intel HD Graphics 4600.
This is my work laptop, and I work a lot with virtual machines with Windows Remote Desktop Connection. I have 2 problems, and they are both related to the drivers.
First one :
I also use my laptop to play, on games like Diablo3 or Nether. I configured games to be played with the AMD GPU in the configuration panel. After a period of time between 20 minutes and 1 hour, the game begins to stutter, the sound crackles and FPS drop to 12/15. If I don't ALT+F4 the game, the whole PC will freeze and I'd have to restart it.
This happens with an old version of the drivers. (126.96.36.199 released on 2013/12/06 YYYY/MM/dd)
To try to solve this problem, I downloaded the newest version of the drivers, currently being AMD catalyst 14.3 Beta V1.0. The game problems are resolved, BUT...and there is a big but. I can't run any RDP connection anymore, because each time I do it, both of my screens go black and I'm good to reboot my laptop. (working on dual screen with my laptop closed)
I also tryed the latest WHQL drivers, but it was worse than the two issues above. I only had 1 screen displaying something, and this screen displayed my desktop multiple times, each overlapping the other. Looked like a full screen of random colored pixels.
Does anyone know what can cause this and how to resolve it? Thank you.
