Massive slowdown

[jhauser42]

I am also experiencing the lag issues on Windows XP. When I start a new character, like I did today, everything seems to run great. Once I leave the first dungeon, Trollmire in this case, and re-enter it the slow down appears. On occasion it gets so bad that just resting for hit points can take 2 minutes or more. This happens on both computers I play on. Pagefiles are enabled. If there are any files you could use from me to track this down I am more than happy to send them.

Recently I played through to the east using a luajit.exe.

The worst areas of the game where sandworm tunnels and dreadfell. I also experienced resting taking minutes.

As to saves I quit using background saves as soon as the option to turn it off was introduced. I save when I enter or leave a dungeon and it works fine.

On the bright side, chrono folding in the few places I used it didn't seem to introduce any extra lag. I used it in Shertul Fortress (and it was a bit slow there, especially when I folded and went down a staircase) and in Vor Armoury (where it worked beautifully, the folding and unfolding barely took any time).

A possible direction to take to help alleviate the slowdown problem.

Is it feasible to save the second previous level to disk on exit and flush it from memory, rather than cache all previous levels in memory?

Eg Character at dungeon level 4
Dungeon levels 1 and 2 are saved to disk
Dungeon levels 3 and 4 are in memory.


That would enable level bouncing without excessive slowdown, and allow the level saved to disk to be decayed when reloaded.

Running windows task manager showed ToME using 475 Mb of memory whilst at High Peak. No wonder things were just a little slow

I tried no pagefile but the game still lags like there is no tomorrow. Like someone said earlier, as long as I can play through the game without saving/loading, then it doesn't lag at all. Is there anything else I can do?

you can build ToME using release configuration it will lessen the burden of maintaining of debug memory allocation granting probably significant boost but bear in mind if something goes wrong well strange things may happen (remember this is still beta phase).

I'm willing to risk breaking my game for less frustrating experience. Can you tell me how I to run ToME in release configuration?

You'll have to build the exe yourself. Here's some instructions.

You'll also need to edit the premake4.lua file so it builds the release exe.

Ok people who have lags can you please try that:
Edit the file game/loader/pre-init.lua and add

Code: Select all

collectgarbage("setpause",100)
collectgarbage("setstepmul",400)
collectgarbage("restart")

at the top of it

Then run the game and see how it feels

I think certain area of effect spells make the game lag. I remember that my summoned fire drake used its aoe on the final level and that the attack remained there. I did not run it from terminal so I cannot confirm this problem. I did notice certain lag because of skill bugs during other testing. This might (or might not) indicate a possible cause.

After some very brief testing in Kor'Pul I can say that there is a HUGE difference! Much better!

I first loaded the game without the above fix and got my normal slow downs. After saving off and then editing the file the game was much better. Again, this was only a brief test, about 2 levels of the dungeon, but I have see zero lags so far/

Works perfectly for me so far - just entered the crypt with a cursed. Thank you very much. I can now turn all effects and shaders back on with 0 lag.

[Canderel]

Looking good so far!... YEAH!!!!

[darkgod]

Yay

It's in for the next beta then!

PS: Oh and since it's in this specific file it wont alter you ability to use online profiles, double yay

I have used it on my b19 mindslayer in the end fight. Before the change every turn would take anywhere between 10 seconds to 3 minutes. Now it runs perfectly smoothly. This certainly looks like the fix Darkgod, tyvm indeed Now I can make myself have one last desperate go at finally killing the PD-ing bastard!

[PowerWyrm]

Works perfectly!
