Its definitely a bug still in the game, with newer hardware.
I've tried several versions of this game (1.17, 1.18., 1.19) on several different types of hardware, old pcs and laptops and newer quad core hardware with pricey video cards.
the old machines recognize even the sloppiest of runes. the new machines can't recognize even the most perfect of runes.
there are lots of other big bugs too, when changing versions/hardware. Bug hate to complain as its rare to see a company keep an old good game alive like this. I'm glad it works fine for most people.

Hmm, I wonder if it's some kind of mouse-smoothing problem with newer GPU drivers. Has anyone with Nvidia card tried setting max prerendered frames to 0 in drivers for this game? Don't know of the equivalent ATI option, if any.

Hey Buddy, I am feeling ya.
I have begin to have limited success with the second rune for the ignite spell. I play in 800x600 (even though I can go to 1600+ if desired) and I draw the second rune smaller than I would have thought. Long lines are more prone to be crooked. Use the same pace, Try to sqare the corners without slowing down. Make sure the make all three lines the same length, like a square without a top. Once I got get better it's about 1 in 10 or less, but far more tolerable. I am sure it will come down with time. Keep em small!

Hello there,

I was playing Arx Fatalis after a long time now again, and I already started a 2nd time because I went too far, and the sisters of ed~ hated me then (so quest failed...no going back to old saves :S)

And now I have another problem, which is, after the dwarven forge, I can't cast anymore spells,
I already reupdated it to v 1.21, I reinstalled it 3 times, I tried it with a HEX Editor, but it literally says me nothing because I don't know any scripting languages...

I can cast the spells, and then it just "bzzzm" 's me and nothing happens, same for the scrolls...
I tried ALL spells , nothing works, and I am barely at the dragon... I can't melt the ice because of this...

When I delete everything and restart, it works again, but as soon as I get my old savefile into the "new" save folder, and start the game -> load my old save -> everything works EXCEPT the spells... and when I restart from that point to a new game, in the new game it also doesn't work anymore...
(and yeah, even tried resolution and all other options... no success)


Please help me, I am in despair... I really don't wanna go through a 3rd time T_T

it would also help if someone gave me just a save file from the ice caves... since... from there its probably the same (same armour and stuff I guess)



Best regards,

the lost arx fanatic, Crateruzzz

Try going back to the dwarven forge and leave a different way - there seems to be a script/level bug that prevents magic from being re-enabled in some cases. Let me know if you find a way to reproduce this issue.

I think I exit both ways... through the normal way and the teleporter, and yea, you remind me of something

Maybe it is because of;

- I tried to use magic in the dwarven forge
or
- a rat man occasionally appeared out of nowhere, hitting me with a poison dagger, and disappeared to nowhere
(and this happens a lot now... but didn't in the 1st run because I killed them all first and then I tried to move on with the quests [ Big mistake ! ] )

Well... anyway, I will try again some things when I finished the game (my 3rd playthrough now ,_,)

I don't wanna mess up another save file...

I will reply in a few days I guess and hopefully find a solution until then...



Thank you for your fast answere!

Well
barely play'd it through, but in the end, of course, akbaa is buggy and he seems to barely one hit me with his spells (draws me near him and I cant even outrun with speed, and then does his lightning sh1t) although i spam the heal button and have over 40 potions..... no chance...

anyway, I consider it done...

and about the problem with the bad save file where I can't cast any spells anymore, well, it is only at this save file but nowhere else now, idk why... no solution there :S

reinstall, replay... only way...

So far~

Just in case anyone else is having this issue, I was able to solve it by switching the affinity to one cpu core

I'm necro bumping this thread to say that this fix worked! It looks like the game wasn't calculating the entire spell movement on one core or something? Before changing the processor affinity I noticed that when I was trying to make the runes, the cursor would seem to "blink out" partway through before blinking back in. I could make it work only by tracing the runes VERY slowly or VERY fast. But when I went into task manager and turned off the affinity for every processor core except 0, it fixed the problem instantly!

I'm really psyched to finally be able to play this game. The magic system no longer seems finicky at all, and actually works quite smoothly.

Good idea--I'm about to try it myself--but it seems this is something the latest build of Arx Libertatis should solve--but apparently it doesn't. Thanks for the idea! Will get back with the results--if I don't forget I posted here, that is...;)

OK, I'm Baaaa-c-c-ck...;) It was merely that I had forgotten to hit the CTRL key again to actually cast the spell after the Runes were successfully drawn! Apparently, the Runes are taken care of in ArxLibertatis--but unfortunately the devs can do little for user's memory, eh?....!

I am stuck with not getting the spells to work.
Wondering if it's just simply a too fast pc and nothing there is to do about it?
I have a Ryzen 9 3900x, quite fast memory and a RTX 2070 Super.

I have tried everything, it seems.
Even disabled everything but one core and restarted the pc and tried.
Used Nvidia control panel to limit frame rate for the Arx exe program.
Launched the desktop shortcut with compatibility mode.

Maybe it's the Arx Libertatis mod - but I don't really want to play without it so I'm stuck even if the vanilla game worked.
Tried the 2013 version of the mod, and the latest 2020 version.
The character seems to say something and it seems the game accepts the correct gestures, with both two spells.
But I'm trying to light the torch in the first area and it just won't happen.
I've been trying about a 100 times, and I doubt it's about precision.
The torch just won't get lit.
