PS: just for fun, 320x200 is not playable, fonts unreadable ;)
This is fully and manly retro :) and i love it, it brings me memories as well. Still i'll give it a shot for 640x480 and see... Thank you

Most of the time it is a steady 60FPS, but occasionally (especially outside) it will just cut to 30FPS. Normally 30FPS would be annoying but playable but it is really noticeable when your FPS just cuts in half all of a sudden. It may be connected to Vsync, as turning that off seems to fix the issue, but without it I get awful screen tearing.
I turned off VSync.... and get no tearing. Check the remainder of your settings.
Screen tearing will vary from different systems and monitor refresh rates. The reason it is there at all is in case you do get screen tearing on your set up, you can enable it to fix the issue.
Agreed....

However the point is, some folks can END the grief in a hurry by simply turning off V-Sync.

Refresh rates became somewhat standardized worldwide with the advent of Flat Screen Digital Monitors.

FPS with V-Sync off ranges from 45 - 120. Fact is, the human eye only handles up to 60 well.. Any higher goes unseen.

The system in use here is an older Intel E6850 with a GeForce GT760ti running on Win 7 64 bit 8gb on a 32" flat screen.

Added Ram helps:
Also many folks are unaware that they can quickly up the available RAM with a 1gb or larger USB mem stick. In W7... plug the stick in and turn on the access.

With v-sync on or off I get no frame rate increase of any kind. Just screen tearing.Turning off SSAO helps a bit, but not enough. I only get substantial increase in fps, if I have everything off. I got about 20-24 fps in some spots, doing this I got up to 32. Changing the resolution made no difference for me. Everything high I get 60 fps in most cases, the forest just hates my computer.

I emailed them, asking if they had any input.

Hi Mike,

The forest is pretty heavy with lots of alpha mapped stuff without possibilities to LOD them out. It's a known issue. You could drop ambient occlusion momentarily off. It makes quite big hit to the performance.

Turning off vsync helped getting rid of the massive input lag and "pumping"(switched from fluid to laggy in seconds) when moving.
Due to how vsync works in can half your framerate(more detailed explanation here: http://www.tweakguides.com/Graphics_9.html ).
Turning on vsync with triplebuffering and prerendered frames (via the nvidia control panel / catalyst control center) i now get a stable framerate - it is not higher - just stable and i do not suffer from that horrible input lag i had in the beginning.

If your computer struggles to get a high framerate in the first place the above may not solve this.

I tried to play Log2 on my old AMD 64 3200+ with my old ATI/AMD Radeon 3850HD AGP card and it was almost unplayable :/ (even more then MMX legacy) If this would have been a turn based game i wouldn't mind it but since it is realtime your framerate matters. There was not much going on graphics wise to explain why the framerate was as low as 15-20. Yes this system is old but i can see in most games why the framerate is bad, but i cannot see why Grimrock performs so bad - even if it looks nice.

Maybe some things can be compiled / hardcoded in a map file so that the cpu/gpu does not have to do everything during runtime, but then the editor wouldn't be so powerful and flexible as it is now(you can change everything on th fly and try it out instantly) without having to compile everything and get a coffee or 2 while waiting for that to be finished - only to see that you forgot something or something is broken... but at least that was a fast method.

Or are the scripts the issue here? Seeing this post: http://www.grimrock.net/2014/03/07/perf ... mizations/
There is an "unclassified" process which used 52% of the ressources. Whatever it is or what it does it seems pretty ressource heavy compared to the other processes.

I still go with the idea of a huge static mesh which gets blended in/out by the lod system, or more 2d objects which gets lodded to their 3d counterparts - but this looks pretty ugly and requires a non trivial amount of extra work just to make slower systems run the game.

Can more things be parallelised so that multi cpu systems are able to profit from their extra computing power? It doesn't seem so right now.

PS.: What is the console command to show the triangles? I guess r_showtris 1 only works for quake ;b
Mr WILSOOOON look i MADE FIRE!
Thanks for the laugh Almost Human :)

He, thanks for reminding on the built in profiler... someone knows if the profiler is included in the Log2 release version and usable via console? Would be interesting to debug what is really the problem in the slow parts of the game...

I have VSYNC forced ON in nVidia's Control Panel. I do not like screen tearing. On a more technical note I also have USWC (Uncached Speculative Write Combining) disabled for videocard. USWC is enabled by default under WinXP and newer.
Interestingly Geforce 600 was released March 22, 2012 so I doubt your system is 7 years old. Just saying...

BTW running super smooth on Athlon II 280 / Radeon HD 7850 as one would expect.

DDR2 and a Agena core (https://en.wikipedia.org/wiki/AMD_Pheno ... _nm_SOI.29) indicating indeed a 6-7 years old system ... guess the GPU was an upgrade. Which is great and the beauty of the PC concept ... no need to exchange the complete system always ;)

You are right. My previous videocard was an ATi Radeon HD3870. The GF GTX 660 Ti (Kepler) is an upgrade.

same problem here, framerate is really low (2 or 3 frames per second, rendering quality set to low and vsync disabled) on a Radeon R9 200 (2GB RAM). gpuz-sensor are looking ok. the funny thing is: if I turn around and look at the old ship the framerate is high and ok, but turning (and looking at the beach) brings it down?! I've 8GB RAM on an i5 with 3.2GHz.

That's either a driver / driver settings problem or a power limit hitting in. Check with GPU-Z if you get green bars in the PerfCap sensor.
