Soooo, I thought I'd get back to you with some more options mostly because my previous fix turned out to be a bust : visuals were fine but I got a game stopping bug because of dgvoodoo2 : the infamous double mouse cursor which prevented me to click on any button of the cockpit !!! Yeah, not that great indeed...
But being stubborn can sometimes work to your advantage and I think I may have found a workaround to the issue... The good thing is that you don't need to use dgvoodoo2 anymore (I really like the program but the less third parties apps, the better for running smoothly our sims).
In fact, all you need is a nglide-Reshade combo!
So here we go (and before this, all credits go to TigerSharky for mostly solving the bug - I'm only adding some tweaks to his findings) :
It is also important to mention I'm not running WIN10 but 8.1 64 and that I have a 1080TI in my rig.
1. Install nglide 1.01 : this version runs fine without any remaining AA.
2. Configure nglide accordingly ( I've selected 1980x1080 with 4:3 ratio).
3. Download Reshade at
https://reshade.me/ .
4. Install the Reshade app --> select the F15.exe in the game's folder.
5. IMPORTANT : you need to choose the directX9 mode (forget about directX10 or Opengl) --> let reshade download the shaders.
6. Before launching Jane's F15, make sure there are no more AA selection in your graphic card control panel --> As mentionned before, you need to DEACTIVATE ALL AA.- DON'T CHOOSE THE APPLICATION CONTROLLED OPTION or you'll still get the terrain tile artifact.
If everything is okay you should have your version of Jane's F15 running with Reshade. You can now activate SMAA in the Reshade settings. It will act as a pretty good substitute to the classic AA thus allowing you to get a great render of the 3D world without the terrain tile bug.
Obviously, you can experiment with Resahde post-process options, that's the fun part !
Some words of caution, here : don't expect things to be hunky-dory each time you launch the sim. Reshade should work but there were instances where for some mysterious reasons (hey, we're talking about Jane's F15, here!) it wouldn't launch with the sim. I had to reboot my PC and everything went fine again. If the last version of Reshade doesn't seem to work, try older ones till you find a good one. I'm currently using version 4.1.1 instead of the latest iteration of Reshade.
A few Jane's F15 screenshots with some Reshade magic :
Cockpit view with fully functional mouse cursor (click-click-click!) :

No more Sea/Terrain tile artifact :
So there you have it ! A not-so perfect solution but at least a viable one. Remember : your mileage may vary on this, but I think it's worth a try.
I can only hope this will be of some interest for those of you who are still flying the Mudhen...
Fly Safe,
