I've had nothing but issues with it. I got it to work once, and now it simply refuses to work ever again. It just crashes immediately. What the hell am I doing wrong?

FINALLY! I'm super fucking stoked but I'm also super fucking overwhelmed. There's so much more to this game than I thought, and I have no idea how things work but God DAMN do I love it!

My game is modded to hell, I have a lot of them. Naturally, due to all the extra scripts and stuff, it played fine, but it had points where things would lag slightly. Plus, using a mod for punching, I would sometimes hit npcs so hard that their bodies would stretch, skew and deform to such extremes it would absolutely tank my fps and crash the entire deck. However, using 9.0, I've noticed the lag is gone, the game feels smoother, and the punching issue seems to have gone away, because it happened a few times on 9.0 but the game still ran fine. I will add, that before using 9.0 I verified the game files. So, my question is, is it the verification or the new proton that has possibly improved the game? I'm still learning as I go with this thing, so I'd appreciate it if you could help me expand my knowledge on Linux and the deck.

Sometimes I hit an npc so hard with the gorilla arms their body deforms, and the game slows to a crawl. When this happens, I have to exit the game completely. When I get to the main menu of my deck it runs fine but putting it to sleep doesn't work, it just black screens, like its struggling to get caught up from the frame drop in the game. Any idea what's happening?

I wrote the lyrics, but the music was the AI.

Back in the day, as a kid, there was a free shareware game that I played an obnoxious amount of times: Graal. Not the shitty "Graal classic" we have today, (it's a shell of its former self), but the original Graal 1.4.0; I searched EVERYWHERE and I couldn't even get a blip more than old forums about the game reminiscing about the "good old days". It's widely believed that Stefan wiped the OG versions of Graal from the map, but he didn't. But not only have I found it, I've found nearly all the player made creations for it:

The site is long since abandoned it seems, but it has EVERYTHING for the classic graal, from clients to server backups to player made levels, etc, and what's more I actually got the 1.4.0 client running nearly perfect on my steam deck. This, for me at least, is my holy grail. I have a lot of nostalgia for this old game from before it got destroyed for the shitty "new" version we have today, and with it a lot of memories flooding back to me. Probably doesn't seem like much because hardly anyone knows or cares about the original Graal, but for me, it's huge, and I just wanted to share I guess.

I keep reading how hard it is to get this game running. I'm still quite new to Linux. Whats the easiest way to get this game working?
