9800gx2 issues with lockon

[RvEYoda]

After som early testing...

Mostly it seems to work fine, however there seems to

be an issue connected with water detail level setting.

 

Below I made a list of settings that give me a good result

or graphics anomalies/bugs. The last one is what I'm using right

now.

 

(with "SLI" below I simply mean using both GPUs on the 9800gx2)

SLI no AA water high : GOOD

SLI AA water high : BUGS

no SLI no AA water high : GOOD

no SLI AA water high : small bugs

SLI no AA water low : GOOD

SLI AA water low : GOOD

SLI no AA water very high : GOOD

SLI AA water very high : GOOD

 

The graphics bugs manifest themselves as flashing water textures, very rapidly and consistently

from certain angles. Disabling AA OR selecting low/very high water fixes the issue.

 

Currently using nvidia 174.53 driver with XFX 9800 gx2 in xp32bitsp2

interesting... keep us posted Yoda.

 

Any interest in going through driver settings and looking for differences? Possibly set your ideal AA AF and in game settings, then look for best visual image quality/performance with driver setting changes.

 

Suspect? --- Texture Filtering - Anistropic sample optimization? THreaded Optimization -Off? .... mere guesses

 

 

How is 3870 X2 (i.e. single card Crossfire) reacting?

 

Our talk on IM's Yoda got me thinking that I do need to jump onto this generation.

Thanks for infos!

 

Because of lack of VRAM on the 9xxx vidcards im waiting for the next gen ( G200 ).

[TorwaK]

9800GX2 = 2 x 8800GTS so it's better to wait for next generation cards as Groove said.

The issue has been coming back and going away. Right now it seems to have

gone away. I guess this is a sign of early drivers. Generally it performs the same

as a 8800 since lomac doesn't support SLI (or so I've heard, naturally I have other games

which were the reason for the upgrade).

However if you are thinking about 9800 and don't play anything but lomac?

Don't get 9800.

 

Another issue is that it seems to randomly select 1 of 3 different performance levels

on starting lomac. ^^. What I mean with that is that I made a reference mission.

I put 100 tanks under my plane where I spawn, then I setup med/high with

4aa/4af 1920x1200 and check the fps.

 

Sometimes I get (rarely): Menu ~400 fps, in pit ~90 fps (if it launches this mode I generally just restart the game)

90% of time in menu I get: ~670 fps, in pit ~105 fps

rarely, but sometimes : menu ~ 950 fps, in pit ~140 fps

It is like sometimes is launches different performance modes.

It seems to launch with these 3 distinctly different levels.

All three with no background processes and with identical nvidia control

panel settings. This card seems to have very immature drivers ;).

 

However those times it does launch "mode 3" (or whatever you want to call it)

it seems to show some pretty insane fps ingame

 

 

And oh yeah, Clouds look like this for some reason =/

it happens after every reboot. The only way so far to fix

this seems to be clicking random buttons (no kidding) in the nv

control panel and then clicking back to what it was as after

the reboot. Totally wierd :)

Lets see if other can confirm this stuff... Interesting though

[5thduke]

im gutted cant play the game like that patch plz lol

[5thduke]

hi yoda i got the 74 drivers those clouds make the game unplayable for me, any way i can disable them cheers

[RvEYoda]

the 74 drivers work,

BUT

you must disable SLI (Multi GPU -> Single GPU) in

application settings for lockon

 

(Sli does not improve lockon performance anyway)

This should fix your clouds :

 

 

This fixes the "flashing clouds" problem.

If you get "transparent clouds" like mine above WITH the 174.74 driver (174.74 should fix this)

then you have some other problem.

Try 8xQ AA

[5thduke]

ty for that trouble you went to yoda i copyed your settings much better still have the flicker but to a less degree, as not to cause any epileptic fits lol, i also turned gpu fan up in rivatuner as cards look like they run hot at stock speed. running 65% manualy seams to drop the card down by 10deg ty.please exuse spelling errors.

[5thduke]

i just removed the cloudgen and clouds file just got a blue sky now, im sweet with it ty.

[RvEYoda]

You still get flickering?

Hmm..

Very strange. You have the latest 174.74 drivers? (not 174.53)

[5thduke]

yeah 174.74 game runs realy nice now ,im not getting ure fps thou srt of arround 30-40 in cockpit.i can live without clouds try the next drivers cheers

[RvEYoda]

Try turning on 4xAA, might help with the clouds

Give a try to Antialiasing Transparency to Supersampling... It should fix the problem ..

 

I had the same problem now it's gone..

 

8800 GTS SLI

8800 GTS SLI

 

for Nvidia 175.16 that did not resolve this issue, but forcing AA to at least 4X, as mention from =RvE=Yoda did fixed it...

 

Weird, not sure what would be the root cause...

 

Anyhow, thanks to all...

 

Cheers
