I had a look at some of games you reported:

Hard to be a god:
not really known game at all, not sure if it'd be worth the effort. It has a really small selection of resolutions ingame, but the config file can be edited manually to set any res up, though anything higher than 1080 will cause ui to disappear. With dgvoodoo ui is present, but bloom shows noticeable offsetting, and double cursor is present too
The bloom rendering technique of this game is unfortunately incompatible with resolution forcing. Without going into the details, it's almost the same problem like the water rendering in Morrowind and Splinter Cell1.
To fix it, it'd require some shader value modifications depending on the effective resolution.

Dragonshard:
very erratic frametimes in dx11 mode, even makes my screen flicker, works much smoother in dx12, but crashes when starting any map with antialiasing enabled in dgvoodoo, ingame option doesn't do anything
I couldn't reproduce this one. I checked out forced MSAA both on nVidia an Intel but the game worked (skirmish map from the menu).

Sea Dogs:
crashes at startup
I remember this game had some problems but somehow I managed to run it, albeit with a bad performance (the game is running for me right now, only the movies are invisible).
Somebody even reported how to solve the bad performance thing. I know it's not too informative, but I cannot remember the solution by heart. Should dig into the game from a fresh install.
