So, shadows are flickering, i have the widescreen fix installed and it didn't work, plus, i've tried the d3d8 to d3d9 ENB, and the latest that DID work was 3D Analyze, but 3D Analyze runs the game vanilla and the widescreen fix does not work with that, so that means FMV's are messed up and hud stretched and bla bla bla, any solution that does not involve any of the previously mentioned?

This is probably the issue I had.

I just described it in another thread on here.

3DAnalyze works with the widescreen fix, but in the current version of the fix you have to rename the widescreen fix d3d8.dll to dinput8.dll. 3DAnalyze injects another d3d8.dll into the game folder, that's why it doesn't work out of the box. Just rename the dll-file, the widescreen fix doesn't mind and works as it should.

Unfortunately for my system, even 3D Analyze didn't completely solve the issue. It definitely becomes much better and nothing flickers for the first minutes of gameplay, but then it still begins flickering from time to time, then stops again after a change of perspective or view.
