Low FPS

[DodoB]

Hi, I'm getting really bad performance in-game, constant dips to 30fps and lower.
I've tried turning on and off different settings, no help.
My computer specs are as follows:
CPU: i5 3570k
GPU: Radeon HD 7950
RAM: 8 gbs

If someone could provide some advice, that'd be awesome :)

Wich OS are you using?
I suggest trying different builds, that usually helps, if you are in Windows, try with Sfan5's builds, and/or Krock's builds.

Your drawtime is high, this may be caused by a bad graphics card or an outdated driver.

Additional to Dragonop's question:
- What's the OpenGL version? (visible in title bar)
-> Search for driver updates for your graphics card

- Did you enable full-range-view ingame? (key 'R')
-> If yes, disable

[DodoB]

Thank you for your responses.

My OS is: Windows 8.1
OpenGL Version: 4.5.13399
I've disabled full-range-view, no help.
I updated my graphics card, not much help.

What's a good drawtime to have?

Thanks again

Ideally, your drawtime should be less than 16 ms. This means you would get more than 60 FPS.

My drawtime is pretty regularly above 32 :(
I getaround 14-18 fps normally, better with a horrible viewing range(5-15)

Looks like you are using "fancy leaves", try with "simple leaves" instead, (if you don't mind, you can use opaque leaves, but that is up to you).
Can you post a screenshot showing your graphic settings, or a copy of your "minetest.conf"?

[kaadmy]

I use simple leaves, opaque leaves look ugly, and fancy leaves cut the performance in half near trees.
Here's my config:

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

aux1_descends = false
connected_glass = true
creative_mode = false
doubletap_jump = false
enable_damage = true
enable_node_highlighting = true
enable_shaders = 0
fast_move = true
fixed_map_seed = pt
free_move = false
keymap_autorun = KEY_KEY_O
keymap_backward = KEY_KEY_S
keymap_chat = KEY_KEY_T
keymap_cinematic = KEY_F8
keymap_cmd = /
keymap_console = KEY_F10
keymap_drop = KEY_KEY_Q
keymap_fastmove = KEY_KEY_J
keymap_forward = KEY_KEY_W
keymap_freemove = KEY_KEY_K
keymap_inventory = KEY_KEY_I
keymap_jump = KEY_SPACE
keymap_left = KEY_KEY_A
keymap_noclip = KEY_KEY_H
keymap_print_debug_stacks = KEY_KEY_P
keymap_rangeselect = KEY_KEY_R
keymap_right = KEY_KEY_D
keymap_sneak = KEY_LSHIFT
keymap_special1 = KEY_KEY_E
leaves_style = simple
mainmenu_last_selected_world = 9
maintab_LAST = singleplayer
menu_last_game = pixture
mg_name = v7
port = 30000
server_announce = false
server_dedicated = false
sound_volume = 1
viewing_range_nodes_min = 35
noclip = true
show_debug = true
minimap_shape_round = false
enable_3d_clouds = 1
new_style_leaves = 0
opaque_water = 0
smooth_lighting = 1
anisotropic_filter = 0
bilinear_filter = 0
mip_map = 0
preload_item_visuals = 0
trilinear_filter = 0
enable_bumpmapping = false
main_menu_tab = simgleplayer
enable_particles = 1
world_config_hide_gamemods = true
font_shadow_alpha = 255


I also have a pretty outdated computer, most OpenGL stuff is slow.

Are you using a high-resolution texture pack? Those tend to lower FPS slightly (it really depends on how big the textures are)
I am not sure about, and correct me if I am wrong, I think shaders affect significantly the amount of FPS and load time.

[kaadmy]

Shaders make framerate about 30% lower for me.
I don't use any texture packs.

[DodoB]

When I set these settings the game runs at 50+ FPS all the time now.

My minetest.conf file:

fixed_map_seed =
mainmenu_last_selected_world = 1
menu_last_game = minetest
mg_name = v6
name =
selected_world_path = C:\Users\DodoB\Desktop\minetest-0.4.13-64a5eec-win64\bin\..\worlds\minetestworld
server_dedicated = false

Calinou, thanks :)

Extra: disable 3D clouds for some extra fps, it usually works :P

@kaadmi, try that :

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_3d_clouds = false
enable_particles = false
enable_shaders = false
leaves_style = opaque
viewing_range_nodes_min = 35
viewing_range_nodes_max = 35

Please note that settings are boolean type (true or false), not binary (0 or 1).

[kaadmy]

Please note that settings are boolean type (true or false), not binary (0 or 1).

I didn't change those, those were put in by MT automatically.

I turned off particles, 3d clouds, made leaves opaque, and I still get around 18-20 fps.

[rubenwardy]

Please note that settings are boolean type (true or false), not binary (0 or 1).

Both work, it's just personal preference. I prefer true/false.

[kaadmy]

And as a side note, Terasology running with lowest everything(Legally Blind clipping distance, 25% render size, 1024x768 resolution, all shaders that I could are off), I get around 5 fps.
So Minetest caters to low-end hardware much better than Terasology :D

and I still get around 18-20 fps.

For some reason, the latest 0.4.13-dev seems much faster than before..
I used to use 35 nodes viewing range at around 20 fps, and now I can get around 25-40 fps with 130 node viewing range..

Have not done any fps measurements on -dev, but just playing it I still notice lot of fps stutter.
