FlyTampa causing me display corruption

Post by Private-Cowboy » Fri Aug 08, 2008 5:20 am

Hi there,

I noticed a very annoying issue with my FSX that I tracked down to FlyTampa sceneries. When I fly to or from TNCM all looks fine and dandy at first but suddenly out of nowhere my scenery textures get insanely blurry and the fonts in the ATC-window and FSX-Menu get scrambled up making em totally unreadable. Only help is to switch AA on and back off and it's all fine and dandy for a short time until it happenes again.

At first I though that this is a driver issue but after trying 3 very different Forceware drivers with no difference at all I noticed that it only happens with FlyTampa sceneries. It happens nowhere else at all including complex sceneries like DillinghamX+Megascenery or anywhere in the FTX Australia region.

Any idea what causes this??? Best regards.

Are you running with sp2 or accel.? Its a bug they added when your frames drop to low it blurs them to beef up the fps. I know its very annoying. I dont know why the made it to affect the menu though.

I think I've figured it out. It looks like the graphics memory and system memory is 'overfilled'. It only happens when I fly my ne A2A Stratocruiser into a FlyTampa scenery. It does not happen if I fly ma Stratocruiser elsewhere but it also does not happen (as fast) when I fly other planes into a FlyTampa scenery. The Stratocruiser is by far the most texture-memory-intense of my planes (80MB of Textures for VC and externals) versus 18MB of the Carnado Mooney or 23MB of the Aerosoft Twin Otter.

It seems that those Stratocruiser-Textures combined with the texture-heavy FlyTampa-sceneries push my graphics memory over the edge. Less intense scenery with the Stratocruiser works well as well as less intense planes with FlyTampa.

Here is how it looks. All is ok...

... and suddenly it goes wonkers...

... without me doeing anything. I've seen that with other planes too in TNCM or VHHX if I try to force it and pan around my plane like crazy causing a mass amount of textures to load. It does no happen under 'normal' operation though. The Stratocruiser seems to fill up the texture mem badly already causing this to happen very early.

What are your system specs ?

Oops, did upload the wrong picture. I corrected that. The issue has been tracked down to a problematic combination between TNCM and VHHX and the new A2A 377. Latter uses too much texture memory (80MB total) and does likely cause this. The thing is neither TNCM nor VHHX are very conservative with its textures either so both combine are the problem. TNCM/VHHX with any other of my planes work as does the 377 over any other scenery.

My specs...

Intel T2500 2*2Ghz
2 GB Ram
80GB Hdd
NV7400Go
WinXP Pro

So this is a laptop?

Yes, a subnotebook. But that should not have to do much with anything. FSX runs well enough and that issue does only occur with the FlyTampa-Stratocruiser-combination.

Try not to read too much into questions. It helps to know these things since laptop hardware is different than desktop hardware. For example I have no idea how much video ram a NV7400Go has.

The video-ram architecture is a bit different. It has 64MB dedicated and a additional 'turbo cache' on demand - which is a fast connection to the main system RAM. However it is not as fast as dedicated RAM and takes away the main system RAM if used.
