DX12 Crash

This issue exists to this day - 23/01/2020.  I have a new build.  i9 9900K. Maximus XI Hero mobo. 16GB RAM. 2070 Super.  Everything else I game plays like a dream - Battlefield 1 - glorious, in fact.  Battlefield 4.  Destiny.  The Witcher.  Warframe. Tomb Raider.  Getting bleeding-edge results in tests.  Download Battlefront 2 and the graphics are shot AF!  At one point, I had dynamic res on and I was getting av. 32FPS with Medium settings on!  I've been looking to mod the game, and there are mods out there, but they're dodgy, don't always work, are tricky to install with few instructions, and people pay HOW MUCH for this game?? For heaven's sake EA!  And how long does it take to fix this issue, or simply make a clear recommendation to users NOT to use DX12??  I was afraid my card was broken at one point.  I can't play the game with DX12 at all.  It crashes the moment the dungeon has been loaded and gaming commences.  Turn DX12 off and it's fine, apart from the fact you have to have dynamic resolution off.  And the frame rates at Ultra settings are terrible.  Unless I'm over-estimating my PC's capabilities, I should be able to play the game on ultra settings at well over 60 fps, and that's simply not the case.  This game needs a serious overhaul, even though it is great.
