If you followed my comments regarding this topic, we are clearly on the same side when it came to the Devs needing to fix this...I've also made references of what I believe to be Nvidia sponsorship to play a role in this atrocity. With all of that said, the podcast I listened to told me what I needed to know for games being ported from console to PC...its not simple. Anything more than that, I honestly do not care. I won't be making any games or porting from one system to the other. The issue that has been repeatedly stated - well PS5 is an AMD APU so it should just simply work on an AMD PC and that is a false. For this reason anything that comes out on the PS5, I buy for my PS5 and games built for the PC, I buy them for my rig.
I don't think it is an atrocity to have a developer back up a sponsor first.
The port depends what you are porting. The driver is basically the same but it does bring features the other cards don't support. You can call it extensions. Then the game itself has the same extensions the driver must support to utilize these. I can assure you it is not a rocket science. I dont think it is false that PS5 would work on PC. It has a different OS than a PC but the CPU could work with a PC no problem. Just because it is software and hardware blocked to prevent usage as a PC is a different story.
It is extremely likely that it is a dev issue, yes. As it's the only game I ever heard of where RT ran (recently) on NVIDIA but not on AMD. It will never make sense to blame AMD for this. It is obvious, as the other guy rightly speculated, that the dev simply preferred to optimize the game first and foremost for Nvidia and release it unfinished, without RT available on Radeon, basically a rushed release - wow, how surprising.
It is not about preference but who you have to please first due to sponsorship and allocation of the product or features depending. I mean, if you have had a business, you would bend over backwards to make sponsor happy since he is investing money into a product and you, as a business owner and beneficiary of the sponsorship, you need to focus mainly on the sponsors product to make it perfect at launch. So NV gets it first because they are the sponsor and AMD will follow later. For me, that is an obvious thing. Nothing wrong or special about it. Of course, the dev could have launch the game with RT support for AMD but maybe they did not have time?
What if there is no sponsor? The game is being released and you have no RT support for any of the cards? The support is being added later in a week or two? would that be OK? you can think of reasons why.
Maybe, the dev did not want to release crap to the customers since these are the so-called sponsors now since they buy the game and the dev does not want any customer to be displeased due to shitty implementation. For instance. That scenario is if the game should have had a RT support from the start.
