HDR on gtx 295 - strange flickering screen

[romeck]

Hi i spoted strange thing as hdr is on, in game it change colours too quickly which couse the screen to flicker, going brighter or darker fast. When i disable one of gpus(which ive read is salvation) the screen is ok but there is very low FPS (ultra + ini mods +mods :( and there is apro. 30 FPS on single gpu. ) Is there a way to solve these problems ? disabling HDR makes game more sad :(

patch?

hot fix?

driver?

screens?

driver settings? ATI has same problem sometimes, I know I do, when that happens, i just turn off driver

[romeck]

pateched to 1,4 (dont want to have 1.5)

what is hotfix ?

newest nvidia driver

you mean me to upload some screen with this flickering ?

how should i change driver settings ? in whaat way ? turn of some values or what ?

[billypnats]

oh maybe thats the problem,

 

Ah, I dunno what its called for Nvidia cards, but theres this driver thing, kinda like a user interface thing in the tray bar, there, you can adjust some of the settings, like AA, AF, etc. mess around with that and turn off some of the optimizations. That usually helped me

 

and yes, screen shots plz

I read this fix somewhere for ATI cards in crossfire having HDR flickering:

 

You have to go to your Fallout 3 game folder and delete the "atimgpud.dll" file. I use crossfire and it works. Not sure about SLI though...

 

Edit: Ah here it is- http://www.rage3d.com/board/showthread.php?p=1336239881

 

This fix has the side effect of making the sky brighter though- so in your Fallout 3 ini file, change:

 

fSkyBrightness=0.5000

to

fSkyBrightness=0.1000

This can also be caused by a weak power supply. Under heavy load, the voltage drops. then as the load is reduced the voltage returns. The card sees the good voltage and increases the load which caused the voltage to drop - repeat. This is usually accompanied by a hot graphics card.

 

That card has not been out long enough for the dust to build up in the air channels, but check for dust in the air channels and on the fan anyway.

As fer drivers you should send a contact to Bethesda an ask them. For one thing Nvida just killed about 500,000 grapics cards this year with a botched driver. Yeah update your drivers. Heh that was only true when it couldn't get us into more trouble than not updating it. If it were me I'd use whatever driver came with the card in the friggan box.

 

Your safest bet in the long run, especially with a big money card like that, is using the "Let the 3D application decide" rather than advanced settings. Heck if the advanced settings were any good to you then you would have already figured it out. Meanwhile you are frying that video card, basicly giving it a half life.

 

Then Fallout 3's LOD is overkill, ultra settings are just for people that are ultra caught up in a pee pee contest. When the game was launched they flat out said it's now rendering 4 times as much on screen than other games. Meaning 1/4 settings yeild a normal experience. But I mean heck you are having a FPS drop just hanging around. What do you think is going to happen when you get into a combat situation, or worse a scripted combat situation. Hence why we turn stuff down.

 

The only Nvida advanced settings that even do any good for fallout 3 in particular is "Override any application setting" for AA an AF, thus providing the supercharged 16XQ 32XQ an such, crisper AF too, but this is the very thing that will half life your grapics card frying it from heat an abuse over a period of time. Certianly in fallout 3, an this Overriding is actually opposite the PC gamer rules for every other game out there.

 

While your in-game settings for fallout 3, particulary the ones inside the default launcher are important. It's not more important than your config files perse. They auto update, but it's possible if you switched out a card to end up with messed up config files. Most people go ahead an take the risk an delete them, then hope they restore next time fallout 3 is launched. I'd just move them an keep them as a back up until the new ones restore. It's kind of like a system scan. It detects what settings you should use, but more importantly it picks if you have SLI mode on, or which shader package is optimal for the card. Then the TweekGuide covers bringing out the rest of the horsepower locked into the Gamebro engine. http://www.tweakguid...Fallout3_1.html

 

The TweekGuide kind of downplays SelectivePurgeOnFastTravel and PreemptivelyUnloadUnusedCellData, but these two and the background loader help to avoid corupted data, while also cutting about 90% of the manual PCB a player would have to do when using crazy chaos mods like MMM natural selection. But like always test it out an see.

 

Defrag yer hard-drive already. Buy norton already, clean yer puter. Then run yer windows auto updates, then when it's perfect. Msconfig an turn off those pesky windows services if you are into that kind of thing.

 

1.4 what, 1.5? Are you searious? That's about the worst idea I've ever heard. It's not even an idea.

It could be an overclocking issue. Tons of games hate overclocking. Which is silly anyway since most games nowdays are very light on the CPU. Your GPU is overclocked too, hence the GTX version, which idk if that plays into the possible cause of a problem. But I do know that most gammers will turn down their PCI-E bus to 120 just to get things a bit more stable. This has nothing to do with your grapics card I don't think, but you would set up your PCI-E bus speed inside your BIOS motherboard settings.
