Yeah, this is a very likely option inclusion: it throws off speedrunning and key-users more than it does someone using the mouse, but it's still important. On the other hand, the lack of smooth scrolling may be equally jarring, since the screen still has to readjust itself every time you move: hopefully there's a way to keep the best of both worlds.

The music is playing but the game freezes for several seconds and then quickly does everything according to the buttons you can press while it is frozen. The lagging is very annoying with fullscreen mode, setting the game to windowed mode makes things a bit easier.

This sounds potentially like a computer specs problem. Can you post your hardware information, like processor, video card, RAM, etc?

Here it goes:

Processor: AMD Athlon 64 X2 Dual Core 5000; 2,61 GHz
Video card: Sapphire Radeon HD 6700; installed latest drivers today
RAM: 4 GB installed, 3 Gb working due to WinXP
OS: Windows XP SP 2

The PC can be the reason, as I have been working under this very OS for a real while and the whole system may be just going nuts.

EDIT: So far special levels cause most problems, namely in locations where there is a lot of blood-stained tiles.

Ratha:
First off, have to say that the new game looks amazing, good work. The new tiles are beautiful, and the custom cursors and things are a nice touch. (Though like most custom game cursors, they feel 'slower' than the standard windows cursor, and seem to operate on a small but noticeable delay, seeming to feel a few frames behind. Not sure if theres anything that can be done about that though aside from allowing the user to use the system default cursor.)

Anyway, im posting here because im having a similar issue to the thread starter in XP on an Intel Q9400 Quad core with 4 gigs of ram and a Radeon X1900. Have to agree with the other poster, that the unpredictable delay in 0.9.9.6g (sometimes its more, sometimes its less) does make playing with the keyboard very difficult, especially as you can easily get multiple moves ahead of the game display, meaning that by the time you see a problem, you've already walked multiple steps into it and cant stop.

It appears that theres a small delay after every movement animation, even on e1m1 with all enemies eliminated, perhaps removing/fixing this delay would help? Im not sure if this is for giving the AI time to move/update, or if its actually caused by slowness in the rendering, those would be my guesses though. It seems like there could be multiple ways (which will hopefully be presented as tweakable options) to fix the issue:

1: By speeding up the player movement and screen-shifting animations, or allowing the user to set how many frames of movement they want to see between each tile / allowing the them to disable it entirely.

2: By not allowing the game to queue multiple movements in graphical mode, requiring that the user wait for the animations to finish before being allowed to make another move.

Anyway, keep up the good work guys. While there are still some kinks to work out, theres no doubt about how visually polished the new release looks. As a result, i think it could easily bring in a lot of new players and supporters, and certainly hope it does.

Pricklyman:
I believe I fixed this via the config file.

There should be an option called "rundelay", I have it set to 5.

I know it's supposed to be for actualy, running, but even on my i5 I needed to set this down before I could press the keys at any decent speed.

(Also, DoomRL graphics version actually does take some kinda high spec stuff, and I'm pretty sure it isn't multithreading either, so dual/quad cores won't help. My dual core laptop runs the game at full screen fine, but with some lag still!)

thelaptop:
I think that the graphics mode still needs more tweaking (there are still some weird bugs to be stamped out), so please report all these anomalies so that Kornel can fix'em up just right.  =)
