How can i force ambient occlusion in old games?

When I had Nvidia card, I could easily force ambient occlusion in any game, I don't think that AMD is bad than Nvidia and I think AMD has some software which allows me to force ambient occlusion.

The reason why I want to do this, because of graphics after forcing.. all objects have shadows and this is too beautiful, it makes old games look better than the original game.

Can you verify what you mean by "Forced" Ambient Occlussion?

From what I read, That settings is under "Options" in the game itself and not part of AMD driver settings, I could be wrong because I am not a gamer though. Also depends on your GPU card if it is capable of using that feature.

Plus how can you force a feature if a game doesn't have it in its settings?

Read about this from this gaming website explaining Ambient Occlusion: https://www.gamedesigning.org/learn/ambient-occlusion/  and  also https://game-debate.com/news/27718/what-does-ambient-occlusion-do-and-how-demanding-is-it-graphics-s... and  What Do All the Graphics Options in PC Games Settings Do? - GameSpot

The game's graphics are hardcoded, outside of open source like quake 2 where people have added lots of new features

When i had Nvidia card, i can just easily open Nvidia Inspector and turn on ambient occlusion feature in any game, including games which don't have Ambient Occlusion support in graphics option. I thought AMD have similar thing, but not HBAO only HDAO, (HDAO is AMD's ambient occlusion)

There seems to be a lot of confusion and dismissal regarding this feature. Nvidia has an implementation where you can, by ticking a box in their control panel, force AO in old games, even if the game itself does not technically support it: https://tweakguides.pcgamingwiki.com/NVFORCE_5.html 
(At the linked page: see first picture for AO setting in control panel; Ctrl+F "Ambient Occlusion" for more written info on it)

Personally, I play an online DX9-based game (Vindictus) that was released in 2010–2011 and is still regularly updated. Vindictus players with Nvidia cards can and have applied AO to their game: https://redd.it/c4fnvw Now, as a caveat, forcing AO on an unsupporting game is imperfect and (at least in this case) it has issues displaying at some angles, but it still is popular and preferred over no AO.

As an RX 5700 owner, I'd be delighted to see AMD implement a similar solution using FidelityFX's CACAO – or at least give crafty users a way of doing that. Is there any way this could be feasible?

AMD is a very poor choice for playing older games, i thought its a known fact already.

Until I got my RTX 2080 I was playing games galore on my trusty old $99 RX 480 8GB

That card took a licking and it kept on ticking, so my opinion of Sapphire, invincible

Sapphire Nitro+ RX 480 8GB

ReShade with the qUINT shader pack use MXAO works in virtually every game who's depth buffer can be accessed, based on Nvidia's HBAO but with better performance overhead and, of course, can be manually fine tuned to add more or darker ambient shading or the draw distance, sample counts etc etc. 

The only drawback is that as it's a post process some games with effects like distance fog can end up with sorting errors (hence the need to tweak draw distance sometimes)

As for AMD being bad for older games, ALL modern GPUs are bad for older games being designed as they are prioritising DX11,12 and Vulkan features and abandoning old APIs and architectural features, in these cases DGVoodoo is your friend.

Re: How can i force ambient occlusion in old games?

dgVooDoo and ReShade do not work together. The nVidia driver engineer considers ReShade errors and develops fixes. This does not apply to AMD. Ask if I'm wrong with. https://www.amd.com/en/support/contact-email-form It's also unclear how effective ReShade plugins are with an AMD GPU.

Edit: If we give the ReShade dll file the name d3d12.dll or d3d11.dll with dgVooDoo d3d9.dll, can it work? I have not tried...

Last: dxgi.dll... ReShade dll should be named dxgi.dll... It works together...  this kind of things open-head...
