Terrain redrawn, disappearing constantly

I'm new to Minetest. It looks great!

The terrain is constanly disappearing and reappearing and redrawn. About three
blocks in front of me whichever way I look. There is also a lot of lag cutting down trees. I've tried about five or six compiled versions and builds but run into same problem. I use view distance of 5. When I go under ground to mine I don't seem to have this problem. It seems to look good only underground.
***(NOTE: Under these conditions)
-Enabled: Bump map, Enabled Normal map
-Enabled Bump map, Disabled Normal map
-Disabled Bump map, Enabled Normal map

So my immediate solution is not use bump and normal maps at all.
One thing I noticed is with only bump maps enabled, graphically bump maps do
not appear. For bump maps to appear I need to enable normal maps and bump maps both. I can tell the difference between bump maps and normal maps, I have
a fair amount of experience 3D modelling.

So far my favourite game is Carbone, but I want to run it with three extra mods in it,
ufo, mob framework and unify inventory.

It almost seems like my computer can't handle the game, not enough memory?

My specs's:
Intel 6750 2.7 Ghz
Win xp, 32 bit sp3
4 gig ram PAE enabled.
ATI 7790 1 gig ram(latest drivers)
GLSL 4.2

Thanks.

Try disabling shaders. Add this to minetest.conf:

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.
Code: Select all
enable_shaders = false


Also make show enable full range or what ever is off. Press 'R' while in game until it says 'off'.

I think this might be the problem.

Actually I retried it again with Shaders enabled and disabled and there didn't seem
to make any difference. They both had same problem.

Win xp?

My computer is capable of playing the latest graphic intensive games without a slow down so why would minetest with blocky graphics slow it down?

I am running the game on a PIII 2,5 GHz with some 1.7gb of RAM under WinXP at times.
It runs well enough to play "normal" worlds. Games with heavy ingame generating stuff such as custom map or tree generating do slow down the machine - as expected.

I seem to have more issues with my slow internet connection that leads to excessive arguements between server and clients to what blocks set are indeed valid. This sometimes leads to blocks being set, then erased and set again several times for each single node. So I might be standing on nodes that vanish under me and appears again after I have fallen through, then to vanish again only to reappear a little later . . . and so on.

I do though have a flickering screen sometimes, as if Minetest cant decide wether terrain should be drawn or not or rather probably the grafic card. I thought this was due to me standing on some border. Usually fiddling with the "+" and "-" key solves that. The map as such is there though. This seems similar to your problems as I presume you are not talking about chunks some 3 nodes away from you being unloaded while you watch.

Besides don't let yourself be missled by the blocky appearance. Loading far views in MT can be a lot more cpu expensive than in some other games with the illusion of details. These are ussually just well done textures over simple meshes with some sort of bumpmapping serving for gritty appearance that might look like complex 3D surfaces. Also in games such as MT, MC and similar, what you see of the terrain really does exist and is editable, while in most other games the landscape in the distance is just a backdrop grafic showing terrain that cannot be visited let alone edited ingame.

@Brockenflabel: increase your view range to 16 (at least) to get rid of that bug.

EDIT: add bold tags around the way to solve this problem.

i have had this problem. try using a viewing range like 15 or 10, because 5 is a bit too short and can be a bit like what you described.

sfan5 is being unpleasant about Windows operating systems. (Particularly referencing that it is an older version, ie XP not 7).

I have to say, Windows XP did run out in April, meaning hackers can easily access your computer (or something along those lines). It's best to switch quickly, just for the sake of not losing all your files. ;)

Windows XP may have run out but I don't have the money to update. I could go linux and do plan on having a bootable linux partition on my system but I will still need windows for my large selection of games that I play. And many of the games that I get now-a-days are from bundles so trying to save up for the new version of windows would take more than a year. Plus the fact that I will need to get a new computer long before I have the money for a new operating system makes it pointless to even bother to get a new windows. Plus you can't get Windows 7 any more and I refuse to spend money on that turd windows 8.

Does this mean your viewing_range_nodes_max is set to 5? This is an awfully low value, it should be at least something like 30.

Your graphics card could handle something like 100 for sure.

My viewing range is 100 for the minimum and 175 for the maximum. I rarely have the flickering terrain anymore. I had a bit in the distance when I think my minimum was 35. Now it works much better.

Thanks, I'll just muddle thru with current setup for now. Thx.

One thing I rechecked was that sometimes it seemed to work without lag.

I just found out when that happens;
--when I play minetest immediately after turning computer on.

But if I surf the net or play a DVD or use any other software then try to play Minetest
there is a major lag or terrain is redrawn. Does this mean Minestest has memory leaks? I've tried three compiled versions that were stable so far but they all do the
same thing.
