Horizontal wave-like distortions (5930G/9600M GT)

Hi, recently bought an acer aspire 5930 with an Nvidia geforce 9600M gt,3GB RAM,and an intel core 2 duo @ 2.00 Ghz.

When I play games I often notice annoying small horizontal wave-like distortions even at the intro videos of some games(Pro Evolution Soccer 09 for example).

I read that it might have been V-sync that cause these horizontal distortions, however turning it off doesn't help at all.

Vertical movement in the scenery seems to cause these wave like effects to occur and I really don't know what do to, I've tried mostly everthing.

I am using Dox's 180.7 drivers, forcing V-sync off etc.


Any answer will be much appreciated.Thank you for your concern guys.

 

try running the game at native resolution. i think you're describing aliasing.

 

My resolution normally (native?) is 1280 x 800 and I did the same on the game's settings also, still the same line appears, going upwards, when switching modes in the menus back and forth.

Any other settings I could experiment with? Would be greatly appreciated...!

 

Try installing Dox's 180.84 (1.1) drivers.

I personally never had issues like you do and I have the same laptop as you do).
Posting a screen-shot of the problem might be helpful though.

Do you keep any electronic devices that could interfere with the screen in such manner btw?
If all else fails, you could always re-install the OS (recovery) or wipe the C drive entirely and install Vista (or XP) yourself.
If that doesn't work either, call Acer.
The laptop is under warranty.

But do us a favor and monitor your temperatures as well using HWMonitor:

Thank you for your well-thought answer but I think that setting V-sync on actually improved the problems dramatically, if not fully. Guess I'll have to lower some of the other settings in order to keep a decent fps.

 

I have the same laptop and also using Dox 180.70. I haven't come across any such problems in Pro Evo 09 or any other games, runs smooth as silk.

As Deks said it might help if you post a screenshot, and let us know your temperatures with HWMonitor. Its free and doesn't require installing.

 

Will do, as soon as I get time, I'm way over my head here with lawstudies today

Is your V-sync on? What is your anisotropic filtering on?

 

I don't keep V-sync on.
Never have actually.

 

At this time:

GPU Temp is 47 centigrades, both my Cpu's are at 47 and 48 each, and my hdd is at 40... seems rather normal?

Deks: I know for sure now that if I turn my vsync off, the waves will appear again.

 

Those temps are good. Hmm, not sure what could be wrong then. Could possibly be the screen?

You mean the v-sync in nvidia control panel? Mine are set to application-controlled, however in games I never use v-sync and ansiotropic filtering is usually low or off.

 

Ok ... so the temperatures are stable.

Which means there are other things left to try:
Testing your memory would be first.
Installing new Dox 180.84.1.1 gpu drivers (and possibly new drivers for other components).
Re-installing the OS through the Recovery option.
Re-installing the OS by formatting the C drive and installing the OS manually from the CD or DVD (XP or Vista ... it's your choice) without the Acer bloatware (have you removed all of the Acer programs btw?).

If none of those options work, then I would say you exhausted virtually everything immediate at your disposal, which means you should back up your vital data if you have any (do this before re-installation of the OS), call Acer, let them know of the issue and have them deal with it.

On another note ... have you installed any programs lately after which you noticed these wave-like distortions on the screen?
Or perhaps a new piece of hardware?

If yes, then try tracing back your steps, re-installing the OS, or even putting back in the older hardware (if you did make any hardware changes) or removing any recently installed programs.

 

Just one thing quickly, just in case you decided to re-install the OS, try plugging it into an external monitor, see if you get the waves, just to rule out if it's the screen or not. If you get waves on the external then you know it's not a screen issue.

 

I have tried it on an external monitor, same problem there... I'm gonna experiment some more with the nvidia control panel.

Ps. Just tried putting the Pes2009 vsync to application-controlled and ansiotropic filtering to 2x (low) and the problem reoccurred.

My temps are now CPU's 58 and 57, GPU 56 and HDD 47....
