View Full Version : Jerky screen?
11-16-2009, 07:21 PM
I'm running an HP a1034n with a P4 3.0 Ghz processor and 3GB of ram (shows 2.36 installed). I've just installed a GeForce 9400 GT PCI video card with 1GB video memory.
sometimes the G5 is jerky, i'm shoing framerates between 73-90's.
Is there anything to tweak in the graphic card? In windows?
I've played with the settings in the graphics menu in G5- low/high etc. I've tried turning all the sounds off....
Any ideas (besides buying a new computer)?

You're getting pretty good frame rates on the high end.
Bear in mind that as your view changes more 3D objects must be rendered by your system.
Something often overlooked is to limit those 3D objects.
For instance NOT using the "keep ground in view" and zooming in a few keystrokes will greatly improve FPS performance.
Also running full screen mode helps a substantial amount, without having to do much else.
Anti-Aliasing can adversely affect performance. There are some settings on the Nvida cards that are handled completely in hardware ( BEST ) and others which bog down the CPU. Always select the Quincunix ( sp? ) modes for hardware support.
Depth of field is something that impacts casual gameplay 3D cards such as yours. Make sure you have it OFF.
Reducing the foliage density has a big impact on FPS, and in many cases can be barely noticable.
Look for and use 3D airfields that have little to no trees off in the distance.
Finally, it is important that other background tasks and programs do NOT take CPU time away from the sim.
If you leave your plane or heli in one spot, and see a periodic drop in FPS, then you have a background task kicking in slowing things down for you.
Terminate such tasks and MAKE SURE they are not set to run when the system starts...
HINT: run "autoruns" on your machine, set it to HIDE "Microsoft" entries and rescan.
What remains behind are things installed by other software that can sap CPU cycles from most programs.
A sweep and deletions by Autoruns in conjunction with CCleaner ( CCLEANER.COM ), can work miracles on some machines.

Sounds like a background task to me. I recommend you contact tech support.

Thanks guys I did have some stuff in the background slowing things down.
I also disabled the on-board video. Don't know if that helped or not.
I also got my new 20" monitor in the mail, so I hooked that up to the DVI port. Before I was running from the VGA port on the card.
With the card set to only one display I'm getting 120-130 FPS!!!I think the DVI port really helped, maybe it's just the way the card works...
