No, I'm using 64-bit as well.

After tweaking some more settings I've got Glide64 to look good! The only problem now is it's very, very slow. Have you got any tips for improving the performance using Glide64? I don't mind if the graphics look poor! As long as the game play is smooth.

Thanks

Well, this plugin is reasonably efficient, make sure vsync is enabled, use no texture filter, and lower the resolution. There aren't that many options for it.

Thanks, I've tried that but it didn't make any difference. I've tried resolutions as low as 80x60! (very, very small) and it's still just as slow. I tried Glide64 in the latest version of Mupen64Plus and it behaves just the same. Here's my config if you can think of anything else to adjust (I've tried changing individual values and nothing seems to help) hopefully there's a combination of changes that will do the trick:

[Video-Glide64]
# Card ID
card_id = 0
# Depth bias level
depth_bias = 0
# Auto-detect microcode
autodetect_ucode = True
# Force microcode
ucode = 2
# Wireframe display
wireframe = False
# Wireframe mode: 0=Normal colors, 1=Vertex colors, 2=Red only
wfmode = 0
# Filtering mode: 0=None, 1=Force bilinear, 2=Force point-sampled
filtering = 0
# Fog enabled
fog = False
# Buffer clear on every frame
buff_clear = False
# Vertical sync
vsync = True
# Fast CRC
fast_crc = True
# Buffer swapping method: 0=Old, 1=New, 2=Hybrid
swapmode = 1
# LOD calculation: 0=Off, 1=Fast, 2=Precise
lodmode = 1
# Logging
logging = False
log_clear = False
elogging = False
# Filter cache
filter_cache = False
# Detect CPU writes
detect_cpu_write = False
# Display unknown combines as red
unk_as_red = False
# Log unknown combines
log_unk = False
unk_clear = False
# Wrap textures too big for tmem
wrap_big_tex = False
# Zelda corona fix
flame_corona = False
# Display performance stats (add together desired flags): 1=FPS counter, 2=VI/s counter, 4=% speed, 8=FPS transparent
show_fps = 0
# Clock enabled
clock = False
# Clock is 24-hour
clock_24_hr = False
# Framebuffer read every frame
fb_read_always = False
# Framebuffer read alpha
fb_read_alpha = False
# Smart framebuffer
fb_smart = False
# Motion blur
motionblur = False
# Hi-res framebuffer
fb_hires = False
# Get framebuffer info
fb_get_info = False
# Clear framebuffer
fb_clear = False
# Depth buffer render
fb_render = False
# Use custom INI settings
custom_ini = False
# Texture filter: 0=None, 1=Blur edges, 2=Super 2xSai, 3=Hq2x, 4=Hq4x
tex_filter = 0
# Disable dithered alpha
noditheredalpha = True
# Disable GLSL combiners
noglsl = False
# Use framebuffer objects
fbo = False
# Disable aux buffer
disable_auxbuf = False

Try disabling GLSL, that's all I can think of. I think the intel card you have is just not enough.

I gave Rice another go (in the latest Mupen64Plus) and found that by using this setting:

# Enable/Disable Mipmaping
EnableMipmaping = False

... fixed my issue and it runs well! Thanks for your help.

Where is this supposed to go, because I added it to the .ini and it doesn't work. Oh, maybe it's only in the latest one ...

Yes maybe that's only for the latest version. It goes under:

[Video-Rice]

... in .config/mupen64plus/mupen64plus.cfg

It's "True" by default.

Yeah, I don't see it in 1.5, it must be in the new one. Well, then that's the solution.

I recently came across a video flicker error a bit different from the original poster, but still very debilitating. I eventually found a fix by changing the screen update function under the Video-Rice plugin.

Default value was 1 for me, and it seemed to not work on my system. Hope this post helps other latecomers!

It did :-). I was getting terrible flicker with Majora's Mask and mupen64plus -- every other frame looked black and the start menu was epilepsy inducing. I'm necro-ing this thread to say 'thanks' as it was at the end of a lot of poorly-documented debugging!
