So ı want to say that ı finally figured out a way to make re4 work on my new gaming laptop. The problem seems to be my screen's rate and the solution to that was re4 tweaks mod that add enhancement and support to the game. It also smooths out the controls and allows fov increase while making the gameplay feel more closer to re5. While it's still limited in terms of design when compared to re6, a good portion of the annoyance feels removed. I will honestly rely on this, it's a pretty good mod imo.
I tried separate ways yesterday but one annoyance was ada was equipped with her new re2 outfit from mercenaries. It was also buggy for some weapons when viewed on inventory and equipping chicago typewriter with that caused the game to crash. I wanted to start with ada's default dress but the game didnt give me the option. I tried multiple methods but no solution to it. It seems that due to playing leon's new game+ with his rpd outfit previously, the game automatically changed ada's to re2 one as well though the cutscenes didnt show her with re2 outfit. I also tried ada separate ways from new game and through that, she was equipped with her default dress.
So what ı did was ı deleted my new save file ( though ı still made a back up for it. ) and ı fully freshed my progress. My save file was also messy due to relying on all separate saves from load game feature and ı wanted to clean those up.
But today ı played as leon from stratch, ı also relied on wemod trainer, that's the only one my pc's antivirus didnt find suspicious anyway. I used infinite ammo and gold cheats to progress. I went up to castle and so far, the experience felt more closer to re5 like ı said previously.
I didnt download hd mod fully yet, ı only downloaded 4 parts. I still have 14 to go. I'll probably beat leon's run 1st using tweaks mod alone before fully downloading the mod then ı'll start separate ways using that as well. That's the main reason why ı'm downloading hd mod in the 1st place, to increase the quality of separate ways cutscenes.
