NC8430 / X1600 - performance lack

Hi everyone,

i just found this wonderful forum

i just got my new notebook - it's very nice except when it comes to gaming :/

her is my problem:

if i start a game (doom3 for examample - ultra @ 1024 x 768) the fps rate sponaneously goes down (from over 40 down to about 12).

i changed the resolution, reduced the quality etc. but this strange behavoir always keeps the same.

i also installed the orignal ati driver (9.3) -> same result
i checked if the hdd was the reason -> same result

at this point i really dont know what else could be the reason for this ...

does anyone have suggestions or maybe eypierenced the same behaviour?

i really appreciate every hint that leads to the "solution"

thanks in advance

 

x1600 used to be a strong card 2-3 years ago, but its glory days are gone and can't run recent games at decent resolution and details. Besides updating drivers and OCing, there isnt much u can do to improve its performance. Try to lower the resolution further, turn off the eye-candies if u want to play games fluently.

 

Sounds like overheating.

I had an X700 card that could play Doom 3 very well on high so the X1600 should, at the very least, offer the same performance.

Check your temperatures with HWmonitor and let it run while you game, along with something that monitors your GPU and CPU speeds. In the case of my Acer with X700, the CPU was the one overheating so I got super low fps every 2 minutes, that lasted like 5 seconds. It was very frustrating.

It was fixed by unvervolting and slightly underclocking the CPU to help with the temps.

 

firstly, that you very much for the fast responese

i followeed the tip of ryzeki but no luck.

so i investigated further:

i lowered the resolution of doom 3 to 800 x 600 (ultra quality, AA off)

and starte the timedemo (demo1)

the behaviour keeps the same - the fps rate goes up to 180 and falls immediatly down to about 10 time after time.

in the end the benchmark tells me i have at average 48 fps?

what else it could be?

thanks in advance

 

Try running AtiTool to scan for artifacts. And Im not so savvy with Mobile ATi cards, is the a section in the CCC where you can underclock the card? Definately sounds like an overheating issue.

Have you tried updating the drivers and restarting to see if it could be a hardware sleep/hibernate etc issue?

Also what temperatures is HWMonitor showing for you during idle and load (min and max)?
