Hi ! I need quick advice, becouse there is one more Leadtek 7800gtx on the stock :D (not much tests on internet, maybe one of You has got this sims on hdd ? )
My rig is down there, i wonder that its really worth the many - i like all maximum settings off course, like water=3 and clouds = 1 in Pacific Fighters or LOCK-ON...

greetings,

Peacemaker.

Well, it should matter in Lock-On which has pretty demanding graphics but I can't see it helping in games like Falcon 4 which contain huge campaigns that really take their toll on the CPU.

The new SLI-AA modes should give you better IQ without sacrificing speed, since most flight sims are cpu limited anyaw.

MIKE C had informed me that LOMAC is a huge CPU Hog. He ran some tests.

LOMAC version 1.2 - F-15 Extreme Track - In-Game Graphics - High - Sound On

Athlon 64 4000+ - GeForce 7800 GTX - 1GB RAM

Fraps was used to record the avg/min frame rate from the first 60 seconds of the demo.

Resolution - 1600x1200

Driver Image Setting - Quality

0X AA - No AF - 32.1 / 19
0X AA - 8X AF - 30.2 / 19
2X AA - 8X AF - 30.0 / 18
4X AA - 8X AF - 29.3 / 17

w/Gamma Correct AA and SS Transparency AA - 28.6 / 17

w/Driver Image Setting of High Quality - 28.6 / 17

That's one heck of a CPU limited game :)

Note: The in-game graphics setting of high has all options at their highest setting except for water (high vs. very high) and visibility range (medium vs. high).
Well thats about what I get with my 6800GT/AMD 64 3500+ overclocked @ 1600*1200 4AA/8AF or without any AAs or AFs.

not an issue, when it scale UP with CPU, it means that you probably have enought juice with the GPU, so SLI might not help
