Greetings everyone,

 

I am writing this post in hope that FINALLY, someone will be able to assist me with this bug regarding FSX-SE... This is an odd one, was searching online for weeks in hope to find someone experiencing the same issue who found a solution or could help me, however, I had no luck... I was troubleshooting the issue myself for days, but nothing worked... What's even funnier is that this is a SECOND COMPLETELY DIFFERENT MACHINE on which I am experiencing this problem... So these are the systems:

 

 Machine #1 (my old desktop PC which I do not own anymore):

• CPU: AMD FX-8350 Black Edition
• RAM: Kingston 2×8GB DDR3 @1866 MHz
• GPU: VTX3D R9 270X 2GB DDR5
• HDD: 1TB @7200rpm - installation drive of FSX
• OS: Windows 10 Pro 64-bit

 

Machine #2 (my current Acer Nitro 5 AN515-43 Laptop):

• CPU: AMD Ryzen 5 3550H
• RAM: Kingston 2×8GB DDR4 @ 2400 MHz
• GPU: RX560X 4GB DDR5
• SSD: 512GB M.2 NVM2 - installation drive of FSX
• OS: Windows 10 Pro 64-bit

 

Both systems and their drivers were completely UP-TO-DATE when experiencing this issue. Now, this is what happens:

 

At some airports that are located near the sea and at a height approximately the same as the sea level itself, I get a strange black patch/water textures that appear beneath me... Nowhere else in the distance, that is all fine, but just in a circle about 100 meters in diameter BENEATH THE PLAYER! The taxiways and runways are spared of this effect, its just the ground grass textures around me that look like that. The airports I currently experience this bugs are LIMJ Genoa (looks completely flooded, as if I landed on an aircraft carrier), LDZD Zadar (bug appears only partially until 1/2 of the runway length) and LDDU Dubrovnik (on approach towards RWY 11 as the terrain is rising from the sea, I get water beneath me as I slowly descend) - so here effect appears on textures that are not in the vicinity of the airfield, but rather on world textures. Strangely enough, I went to KJFK and test if this will happen there, as I know it's all surrounded by water, but nothing, no problems there even though it's graphically and CPU 10 times more intense than those other areas...

 

Here are some other differences that might help: my machine #1 was running FSX-SE on DX9 and settings set on high, almost no major addons, just some freeware aircraft and world textures. My current machine #2 is running FSX-SE on DX10 with Steve's DX10 Fixer, ORBX Global Base, FreeMeshX and Aerosoft A320X... However on my first machine, under DX9, these textures were not replaced with water textures, but it was just black patch that was following me all around, even further than what's happening now... Here is the link to screenshots taken at LDZD, where you can see the problem just appears partially on the southern side of the airfield (at 1/2 of the runway length, no matter the altitude problem goes away), the patch follows me around, as you can see my initial position at the tower turns into the ground when I slew to to left, and if I taxi on the "water" itself, it detects it truly as water, not just texture replacement of the ground: https://postimg.cc/gallery/8MqPmFC

 

When did I notice this problem?

 

On my first machine, the problem appeared after I installed "World of AI" complete pack, and now on this machine after I installed "IVAO MTL" library... They are both pretty big (around 6 GB), and after installing it the FSX-SE takes about 5 minutes to launch the first time. Upon their removal, the launch is back to normal, but the problem persists... I do have edited fsx.cfg, however, this shouldn't be the issue as my last system didn't have it edited and on this system, I have been playing for almost half a year now with it edited, and the problem just appeared out of nowhere last week... I tried to edit the setting in Radeon Adrenaline Software, however, nothing helped... I deleted the shaders cache but even that had no effect to it... Strangely, if I replace an airport with an addon scenery of it, that has photoreal textures around it, the problem goes away (example of LDZD), so I assume it has something to do with scenery hierarchy or so... I truly have no idea at all...

 

I don't know what is causing this strange issue, if somebody has any idea on how to fix this I would be extremely grateful 🙂 I wish you all a nice rest of the day, and take care 😉

Well, the one most simple and obvious solution I forgot to check is decreasing the "Texture Resolution" setting under the "Scenery" tab within FSX's "Display - Settings", go figure 😅 I feel a bit stupid now, but apparently my VRAM doesn't really appreciate 15 cm texture resolution I was having until now... Decreasing it down one notch to 30 cm texture resolution fixed my issues on all airports where it appeared 🥳 Basically, out of interest, I tried bringing the value to 7 cm (max setting), and the water patch became even bigger 😅 I guess as my older machine had 2 times less VRAM than this one, is why I experinced this isue more often back then 🙄

Well I hope this will help someone having the same issue, and spare them all the trouble and time I spent troubleshooting this, even though the solution was under my nose all the time 😂

Glad you got it sorted out!

The more simobjects ( any type ) the longer it takes to load. When flightsim starts it inventories each and every sim object by reading every aircraft.cfg / sim.cfg entry and cross checking them with the sdk simobject container requirements.. ( model found?, have a panel?, flyable?, sound found? etc... )
