Oh. I see. I have seen some titles with very good D3D performance.

That would actually surprise me since OpenGL has been measured to be faster then DirectX since years up til today. Also OpenGL support is build into the regular video drivers. For example the current nVidia driver 340.53 which i updated to about a week ago adds support for OpenGL 4.5. Of course the GPU hardware needs to fully support it to benefit from anything that version offers.

With OpenGL being the GPU access method outside the windows world i wonder why AH won't go that route from the start. It would save the need to port DirectX related things. Also looking at the uped hardware requirement OpenGL 3.3 and higher is available in those GPU's; no need to dance with LoG 1 OpenGL2.x limitations anymore.

Will it run @ 60fps in 3d @1440p ultra settings?
Specs are amd fx-9590@5ghz
16gb 1866 cl8 ram
Amd r9 290

60 fps 3d in HD+ with 1 R9 290? Sorry, no way and that's not only for LoG2; this means in general.

One R9 290 might be powerfull enough to deliver 60fps 2d in an HD+ resolution, depending on the game being run and the detail settings choosen, but it definately can't deliver 3d respectively 120fps. If 3d is your goal in HD+ you will need at least 2 such or even stronger GPU's linked in Crossfire-mode.

logr 1 (not sure about 2) is not written like most 3d games.. basically.. Get a video card with a good pixel fill rate (good 2d speed).

I think it moves large bitmaps rather than draw lots of triangles. It looks good because there are no stupid polygons.

Modern 3d cards a written for small polygons. Something that can quickly drag pictures around in paintshop or photoshop is trickier to find.

p.s human eye can only see 48fps so 120fps is pointless.. i think your eyes and brain process at 12fps.. 24fps looks smooth of every second frame is black.. 48 looks smooth

This is news to all the modders that imported polygon models into the engine; no it is certainly a polygon based engine.

The snail is the simplest monster in Grimrock, and that's got over 2000 triangles in it.

I mean the walls. It is when you rotate past lots of walls the gpu fires up.

I was just trying to work out a few years ago why all the people with maddx5 cards were complaining... I just assumes that something like large textures or large poligons for the walls or transcendentals with floats was the cause. (and I have a maddx5 card, but no problems because, I got one with the highest pixel fill rate at the time for 2d gaming)

I see they got rid of floats so maybe it will work better. (log 2 is using integers instead of floats for transcendentals, so it will be interesting)

(Sorry I am not a game programmer, just a normal programmer, so it is a bit hard to talk about)

The walls are simpler, but still polygon models; it looks great because the huge normal maps make a difference.

That's not good ~if it also means that model positions can't be floats.

you lost me there... but just the ones they don't need... maddx5 cards are optimized for integers not floats, (it is 5x more work to use a float which was my theory)

maybe it is the "huge normal maps", anyway if that is what gives it the 2d feel, I hope log2 has the old school 2d feel still

is a "huge normal map" a large bitmap?
