Fallout 3 low FPS on 4850


Iv000

Recommended Posts

I am heaving fps and stuttering issues on my PC.

Specs:

4850 512mb

Phenom x2 @ 3.4 ghz

4 gb ram

21.5 inch monitor (1920x1090 resolution, i cant set it down because it will get blurry and pixelish)

 

Most of the time my FPS are ~25 and there is lots of stutering when moving/turning the camera..

I read on some forums that people with 8800 have 60 FPS with all max.

I know ATI has some problems with Fallout and Oblivion.

What i did was to disable water refractions and the FPS jumped +10-15

So now about 40 FPS but still stuttering a lot, are there any more tips to increase FPS on this card?

 

(PS Crysis runs on 35 FPS on high, so its not my PC)

 

I forgot to say, i have the 8.6 drivers i heard bad things about the new ones...

 

Thanks!

In Full HD resolution a 4850 with only 512MB is to weak for Fallout with max. settings. You can try to run F3 in a smaller resolution windowed. Try 1240 x 1024 with all settings at maximum, that should be okay.

I found a "fix" for my problem, I renamed the Fallout3.exe to oblivion.exe ( i found a topic about that in some other forum) and now it is running all max (AA is turned off) 1920x1080 on 54 FPS!

And i dont think that my 4850 is too weak because if i can run Crysis on the same resolution and high with 35 fps than fallout should be no match. IDK why but it was the water refractions option that was slowing down FPS by 14.

Some ATI cards dont like the Gamebryo engine or vice versa.

But anyway thanks that you tried to help!

 

Looks like the best answer to my questions is and will always be google.

Renaming in Oblivion.exe is helping? Sounds like the CCC is limiting the card in that game..., or there are some tweaks inside working for Oblivion and so the are helping F3, too. Will have a look at this, too. I'm using a 4870 and had some issues with frame drops. I never tried other games like Crysis so i thought F3 wants to much...

Thanks for posting your solution, will give it a try on my machine.

Make sure your AA isn't set to Super-Sample, that clobbered my frame rate, switching to Mulit-Sample made a hell of a difference. (ATI 5870 1GB)

 

Yes i fixed my FPS issue, but now the game keeps crashing (I really dont know why).

As you can see in my new topic. ( I know...i am spending more time on trying to fix the game than playing it)
