[Løst] Min Alienware m17x R4 lagger


Anbefalte innlegg

Hei, jeg har en Alienware M17X R4 med disse specsa:

 

2GB GDDR5 AMD Radeon HD 7970M

Intel Core i7-3740QM

6144MB RAM

 

Maskinen kan spille Skyrim på Ultra med mange mods på 60 FPS, det samme med Minecraft og League Of Legends (uten mods).

Men når jeg skal spille spill som Dead Island, DayZ, Arma 2 og WarZ går FPS ned til omtrent 10. Er det noen som har noen forslag til hvorfor dette skjer og hvordan det kan fikses?

 

Takk på forhånd!

Du kan nok satse på at det er slik som Spoki0 sier. Sitat fra Notebookcheck:

 

"AMD's GPU-switching technology, recently renamed to Enduro, is not nearly as polished as Nvidia's Optimus system. For one thing, Enduro is short on configuration options and for another, automatic switching shows a poor rate of software recognition.

Of the 19 games tested, 60% were started with the wrong GPU, Intel's HD 4000. As a result, the user has to go find the right menu in the Catalyst control center (see image) and assign the program to the correct GPU by choosing "High Performance" in order to have it run the Radeon HD 7970.

It is not obvious which GPU is currently active without additional tools like the AMD system monitor. Nvidia's Optimus feature offers far more polish and useful features. For people who prefer to work or play without automatic GPU-switching, Alienware included the Fn + F7 function key, setting the system to always run with the dedicated GPU (reboot required).

Nonetheless, AMD should finally get their act together and improve their GPU switching software. Disappointingly little has happened over the last few months and Nvidia can only smirk about its competitor's lack of progress.

Note: due to the Radeon HD 7970M delivering markedly worse results with automatic switching activated, we advise to make use of the function key and turn off GPU switching for gaming purposes."
