NVIDIA GeForce 9400M G Graphic Card Problem

Asked By 390 points N/A Posted on -

Last month I had an issue regarding in playing online games which I never had before, it consists of accentuated decrease in the FPS rate which is impossible to keep playing. I’m doubtful that it is due to my connection because I used to play with no hassles. And so I spent whole day to reinstall programs and restore to its factory definitions, but the problem still persists.

Anyway I’m using Acer Aspire 5737z with a graphic card NVIDIA GeForce 9400M G. Here’s the scenario:

As soon as I start the game the fps rate is about 60 which I think is fine, then at 20 minutes of playing or less, it drops to 30-40, and then it abruptly decreases to 7-10 fps which obviously an unplayable game.

By the way the game is League of Legends, and I don't think there's a host system, so I don't know to which extent it could be the cause of the problem. Any help please?

NVIDIA GeForce 9400M G Graphic Card Problem


Hi There!

  1. Which League of Legends server are you currently playing on? EU, NA or SEA (Garena)?
  2. Does the drop of FPS happen to other applications and  other games as well?
  3. Have you tried reinstalling League of Legends?  This may sound like a generic solution, but 50% of the time if there is a problem in League of Legends this solves it.
  4. To find out if you are having a video card issue, there is a simple way to test this.  Go to YouTube and try loading one of the HD Clips from Game Trailers or Movie Trailers and see if you get a Green Screen.  If this happens then your driver needs updating or reinstalling.

Here are some solutions for the mean time

  1. While in-game, adjust the video settings into a smaller screen resolution and see if the FPS raises a bit.  Allow a few seconds for it to change.  Try even a smaller screen resolution if nothing happens.  If there are still no changes, check your video card settings and maximize performance over quality and see if there is a change.
  2. Try the game windowed mode and see if there is a difference as well.  While windowed check the running FPS outside if they are consistent in-game.
  3. Check your video card settings and set the FPS you desire (if you haven't done this already)
  4. League of Legends still experience a lot of compatibility issues when they do their updates.  If there was a recent patch (either new champion or nerfs) it can affect your game play to some degree.  How?  NVIDIA has a built in firewall which for some reason RIOT forgets from time to time to consider.  Uninstall this by Add/Remove or reinstall and choose a custom to have it not installed.
  5. Check if you have sufficient memory in your hard drive that League of Legends is installed on.
  6. Update Adobe Air which League of Legends uses.
  7. If it still gives Low FPS, alt-tab while in game and open your task manager and end the process explorer.exe.  Your icons will disappear but they will return shortly, alt-tab back in-game and see the difference.
  8. Another way would be to openup the task manager (Ctrl+Alt+Del), click on the processes tab.  Find the League of Legends processes, there should be two, lol.launcher.exe and LolClient.exe. Right click on both of these processes and select "Set Affinty".  Once you click "Set Affinity" there should be a window where 2 boxes will be checked.  Most of the time, these will be CPU 0 and CPU 1. Uncheck one of the boxes, I prefer to uncheck CPU 1, but I don't think it really matters which one you uncheck. Be sure to leave at least one of the boxes checked.  Hopefully this will fix it.

I'll be watching this thread so respond when you can.  I hope this helps

Play the game without using online. If the problem remains the same, then there is an error in the video card. If not, there is a problem in the connection or the server. When your net connection varies, this FPS value could change. This error also can be checked.

Use another net connection (your friend’s) and check whether it works or not. If the problem is in the connection, update your drivers or ask your service provider.
