Hi,

 

I was taking a trip from HongKong to Tokyo (VHHH-RJTT( and about 2.5 - three hours in the flight i was getting these artifacts with very very bad scrambled textures. Same thing happened after 3 hours during a EGLL-OMDB.

 

The strange thing is that it´s occurring over water in FL390 were the "load" is pretty much low. I dont see this in heavy scenery (for now).

 

Might be overclocking issue or RAM?

 

The temp on the GPU is about 55-63c and 70-75c on the CPU (i7-4770k)

 

Anyway saving the flight and just restart FSX and there is no problems. Heck the flight seems smoother anyway after this reload.

First do you have HIGHMEMFIX=1 in your FSX.cfg ?

That sounds like a heat problem on your graphics card or processor.

 

1. If you're running a desktop, it's time to check the filters and inside the computer for a good cleaning. Not saying this IS the problem, just running down the list. If there is a lot of dust, I don't recommend using a can of compressed air as that will blow dust down into tiny cracks and such. Unplug the computer power and all cables going to it, wait three or more minutes, and then vaccum out with a plastic computer vacuum adapter.

 

2. Check to ensure the computer has adequate airflow for cooling inside and outside the case. Some people forget that where you place the desktop can be just as important as the internal cooling.

 

3. Maybe this should have been #1, but if you're overclocked then try reducing it, the artifacts could mean that you're running past the capability of the processor chip. Note: This could also be true with a non-overclocked processor though this is rare.

 

4. The graphics card may be on it's way out. It happens and though rare these days, this could be true of a newer graphics card. If none of the steps above fixed the issue, try swapping to a new graphics card.

 

Well, those are the starting points, and will fix 90% of such issues.

 

 

Hope this helped.

Be VERY careful with "plastic" vacuum adapters.

 

Vacuum cleaners generate high velocity air... through a plastic adapter generates static electricity.

 

This is why cans of pressurized air are recommended.

 

Personally, I do use a vacuum cleaner, but with great care. But around sensitive components I use a can of air.

The temp on the GPU is about 55-63c and 70-75c on the CPU (i7-4770k)

70-75C while running FSX is very high. If you were running a stress test I would imagine that temperature would be dangerously high. What is it when running a stress test, 90? 95? Would be throttling back at that temp.

 

Your GPU temps look okay.

thanks will but the CPU back from 4700 to 4500 for a while and see  B)

 

Michael Moe

True about the vaccum head, though it's not as much as one might think. Still, as I and the person who replied said - DON'T TOUCH ANYTHING.WITH IT.

 

CAN OF AIR:  No sir, not ever inside a computer case. Please, no. As a computer hardware engineering type (one each!) for somewhere around 30 years, I can tell you that those cans of air are banned at facilities around the globe (even just places that run PCs) for the damage they can cause.  Just a very bad idea... but I'm not saying that the companies that sell them aren't doing well. I wonder if hardware companies invest in or own the Can-o-Air companies?  LOL!

 

Anyway, just can't go along with that professionally. Best solution is not to allow dust in to begin with (yeah, like we can all afford a clean or near clean room like we had at IBM Federal Systems Division).  I run simple filters on the outside of my desktop and on the internal fans - especially the radiator fans.  I clean the external fan filters weekly, and the inspect and clean the internal filters monthly or as needed - but I live in an order place with carpets, so we know what that does...

 

 

I'll say this though.  EXCELLENT TOPIC!  We don't hear enough about this important area. Worth every penny for filers and every minute cleaning them.

 

 

Dave

Take it out side and clean it with a leaf blower.....take about 3 seconds, all done :blush:

Man, that got me laughing!

 

 

No way to really know, but I suspect his system air cooling is the culprit here, either because it needs a cleaning, the system isn't drawing enough, of the fans are in conflict airflow wise though not "badly" because it destabilizes after two plus hours.  That would explain why it happens after a few hours, and not when at an airport (higher graphics processing demand). 

 

The overclock could be a contributing factor (so often it's more than one thing). If it was just the overclock, he'd probably have problems pretty quickly.

 

No matter what it proves to be, I hope he's able to resolve it.

These are the most likely causes:

 

1. Out of memory

2. Overheating graphics card

3. Your hardware is out of balance - i.e. good processor, bad GPU - combining that with Bufferpools=0 will "starve" your GPU and will cause artifacting. 

CAN OF AIR:  No sir, not ever inside a computer case. Please, no. As a computer hardware engineering type (one each!) for somewhere around 30 years, I can tell you that those cans of air are banned at facilities around the globe (even just places that run PCs) for the damage they can cause.

 

 

Can you point us to a link for that? Sounds like interesting reading. Can's of air are fine in my view, but like with anything care and common sense is required.

I think most of us are running with filters, they do help, but dust still gets in. can't be avoided. Fine dust through the filter, and dust through small gaps. Dependant on case pressure of course.
