Changing game engine and DX version

[Simon771]

So I'm playing this game called Black desert online (BDO), and they have some pretty bad optimisation.

There was some talking going around the forum, and people are asking for new engine and update from DX11 (feels more like DX9, since it doesn't seems to use multithreading, but w/e), to DX12 or Vulkan.

Can game even do update like this? Or would they need to make completely new game?

And if it's possible to change DX version of current game, would they be able to just push "normal" game update that would change that?

 

What about game engine? They are using some Pearl Abyss engine, but would they be able to change that also? With "normal" updates?

 

I belive changing from DX11 to DX12/Vulkan and chaning game engine would mean that developers would have to rewrite 90% of the game code, so it would take long time. But how long exactly would it usualy take to change that? Are we talking in few weeks/months/years?

 

I apologise if I sound dumb, but I don't have any knowdelge of that so I rather ask here

If they are using a game engine that gets an update for a newer DX version, the upgrade is usually pretty simple (relatively to reprogramming the game). If they would have to reprogram the game in another engine, it gets a lot harder.

I'm pretty sure they are not using engine that would allow the to update DX version that easly, otherwise they would probbably do it already. Players are complaining all the time about low fps in crowded areas. Having best PC, and see 20fps in-game just makes me sad. Meanwhile CPU and GPU are sitting not even on 50% usage. And ofc. chaning game settings donesn't work one bit.

 

It seems like they would have to use other game engine if we want to ever see stable 60fps all the time.

Unfortunately, the API and engine aren't exactly "together". The API could be easily changed to DX12 for "more logical cores", but it would do nothing if the engine is "working" on two cores.

I don't get down to 20FPS, not at any time, the game seems decent, however I do agree that no multithread sucks ass. It also gets my loop hotter than any other title/test out there, especially the GPU  - seen it up at 67C which is hot for my loop and again, with only around 50% utilisation

So in the end they would have to use new API and engine if we want to see any performance increase.

Sadly I don't think they will ever do that, because it would cost them too much.

I get even to 15fps at Calpheon. That city just bring my FPS to it's knees.

When grinding mobs etc. it's okay at around 50-60 fps. But even in those scenarios I don't get why fps is dropping.

Overwatch have no problems with that ... I got stable 75fps with vsync on my 75Hz monitor, regardels of how many players were around and spamming skills/effects. FPS was always stable at 75.

So I kinda notice every single fps drop in this game, and it's bothering me. I realy like this game, if they could only do something with engine to deliver me 60fps at all time, that would be just fantastic.

Would even pay them money for "DLC" with better engine lol

The things I would do for stable 60fps

Just a new engine is needed. The API doesn't do anything more than the engine allows for. Wanting DX12 for better use of logicals is good, but the engine must support and be coded for it. If Minecraft went DX12, the performance would barely increase since the engine is single-threaded (which means that calculations are done in sequence rather than in parallel, not that it uses a single core).
