I upgraded my PC a while back, which I never had any problems with, to a new one which is driving me nuts. I believe I'm running out of video memory, as panels and textures disapear.I have a GeForce GTX 275, Q8400 CPU, 4gb of mem.Does anyone have any tips on reducing the chances of this happening? Changing FSX detail settings doesn't seem to help much.I've heard disabling the onboard sound and getting a seperate soundcard can help, I just can't afford that right now.

Unlikely that you are running out of VRAM, unless you're running an absurdly high resolution with massive amounts of AA. More likely to be a driver issue or a faulty card. Try a different driver revision and see if that helps.

Try modifying the line in the FSX.cfg file:TEXTURE_BANDWIDTH_MULT=40 (your default? yes?)And change in steps of 20 and see if that helps you or not:Change to TEXTURE_BANDWIDTH_MULT=60Last night while testing some other settings I flew for over an hour with the GPU memory pegged at 1018 MB and GPU load of 67%, still never ran out of buffered textures, could cycle all views and the textures were all there.Did it flying some pretty high settings, Super Sampling AA and high Lod values <all for testing purposes on the issue of Black Screening with demanding add-ons like FSDT JFK while in high-end AC models, CS/LevelD/Posky/PMDG etc.Try the Texture_ multi settings of maybe 60/80 or even 100 and see if that helps, don

Thanks guys.

I've tried updating drivers which didn't help, so hopefully it's not a faulty card :(

Checked my cfg, it's set to 90 :(Set to 40 and take if from there?

Yeah, give it wirl!When things go bad, go back to default and work from there.

Still getting problems. I've tried 40 and 60 and I'm still losing textures. :( Any way to check my gfx card? I don't seem to be having problems with anything else. dxdiag is reporting 2668mb of mem which is weird though, the card should have 896mb (or around that, can't remember the exact number).

Post you FSX.cfg in here as well as your driver settings for display, and include any toher settings, Enhancer etc. and we can have a look and offer you some suggestions based on that, othewise its just a big crapshoot.

I have latest driver version, 196.21. Using 1920*1200 in windows, 1680*1050 in FSX. Looking at nvidia control panel, Antistropic filtering is 16x (turning this down likely to help perhaps?) FSAA is set to application controlled.I've included the bits of the config I think are relevant, let me know if I should include anything else.

There is much more to it, no pun intended.Please post the whole cfg.16xAniso is good, dont change that. application AA is not the best, but ok, but before we address that we will try to get you up and running to solve the problem at hand.When you post the cfg also post info about what flight and aircraft you load or what ever best describes the scenario when you run you run out of memory.

I've had it happen with the following aircraft:PMDG MD-11PMDG 747Level-D 767Eaglesoft Citation 2.0 XThink that's it.Usually happens when switching from fullscreen to window and vice-versa, or changing viewpoint.Full config below.Thanks for your continued help!

I've had it happen with the following aircraft:PMDG MD-11PMDG 747Level-D 767Eaglesoft Citation 2.0 XThink that's it.Usually happens when switching from fullscreen to window and vice-versa, or changing viewpoint.Full config below.Thanks for your continued help!

Great.Ok, well there are a number of things to spot and some of these are worse with your add-ons if you are on Win7-64 but either way some things need to be addressed.Two stand outs right off the bat are:1.You have multiple video card entries.2.TEXTURE_MAX_LOAD=4096, your asking FSX to display texures that are bigger than stock by a factor of 16, so putting this back to =1024 would be a good starting point, if things go well, then bump it up to =2048 etc.It just might be a good idea for you to let FSX rebuild your cfg and start over.To do it save a copy as a backup (rename it Bak etc), then delete the original and let FSX rebuild, you will have to go back and adjust your settings as well as verify the "trusted" gauges and dll etc of the various add-ons as you load them. Or, just delete all the "display" entries at the bottom were your old card is listed and just keep the one that matches your 275 and screen resolution and color depth, follow?

I'll have a play and see how it goes, thanks!

I noticed DX10=0, meaning your not using DX10 Preview. I know folks have very mixed emotions on checking that box (for me, it gives stunning improvements in FPS at 1680x1050 with a GTS250 1MB - no mem problems...ever).Just a thought - maybe try a flight or two with DX10 Preview checked?Cheers

Not flaming you, but that doesn't really address his problem at all, a kin to someone with a misfiring engine in a car and we suggest to him a nice new polished and ported intake manifold...or a leather wrapped strearing wheel.Further DX10 preview is broken, as much as it improves somethings it breaks others like all the flashing runway textures and the fact that you cant over-ride filtering.It is a real shame that FSX did not get the full DX10 treatment and support.

Paul,Not a flame either, just IMHO, but after looking at his setup and gear, it indeed seems to be a simple step in the troubleshooting process to take - a step from which he could learn much. His kit can certainly handle it (DX10) as it it quite a bit more up-to-date than is typical for folks who have the problem he is describing.So, quite the contrary of suggesting "polished rims" or anything of the sort for a mis-firing engine - I'm suggesting he look at his engine management software (to continue with the analogy). Absolutely appropriate and on point to the issueSo, bottom-line, even though it is considered a "Preview" (I'd very much dispute the 'broken' assesment, though, as I use it every day with no issue and with zero 'tweaks' to my .cfg file) it is a troubleshooting step that does not cost any $$$ to try, is easily "undone" and is indeed a superb test as it utilizes a completely different vid software graphics architecture...indeed the one for which his vid card is designed for (DX10).What's to lose by checking that box and taking a fly around the circuit? Nothing.Let's here from him - I hope he gives it a try - up-to-date graphics driver, 'fresh' FSX generated .cfg & the DX10 box checked - and posts us with the results, good, bad or indifferent. I'd wager he just might be pleasantly surprised...Cheers!
