Modpack Endless Loading Bug

[enterprise12]

My friend has been trying to play my modpack Industrial Age The Turning, he has a problem no one else has, the pack loads, but stops at a certain point for an hour before finishing.

looks like it has trouble loading the textures.

Here is a small snippet of where it takes forever to load.

[17:26:06] [Client thread/DEBUG] [FML/]: Bar Finished: Texture Loading took 16.259s
[17:26:10] [Client thread/DEBUG] [FML/]: Bar Finished: Mipmap generation took 4.398s
[17:26:10] [Client thread/WARN] [FastCraft-core/]: The sprite Chisel:snakestone/obsidian/particles/7 caused the mipmap level to drop from 4 to 3 because it's too small (8x8 px).
[17:26:10] [Client thread/DEBUG] [FastCraft-core/]: bufferTextureUpdates = true, 33556480, 1073741824
[17:26:10] [Client thread/INFO] [EnderCore/]: Removed 0 missing texture stacktraces. Tada!

[18:43:40] [Client thread/INFO] [FML/]: ROTARYCRAFT: Loading Liquid Icons

[18:43:40] [Client thread/DEBUG] [FML/]: Bar Finished: Texture creation took 4649.699s look at that load time, it took 1 1/2 hours about to get to the next step and finish.

hundreds of players play my pack, and no one has had this issue, it loads in 2 minutes normally even on really crappy computers, his has an I5-5200U 2.2Ghz not the best, but certainly shouldn't stall it like this.

I appreciate any help or feedback you can give because im stumped, thanks!

 

[enterprise12]

He has plenty of RAM assigned to both launchers he assigned 5gb max out of 11, when my pack only requires as little as 2gb minimum

I fix problems everyday for users being a big server and pack owner, im quite stumped on this issue. He has the right version of java 8 jre 64 bit, hes using Windows 10, which maybe could be a bug in the system since its fairly new, but idk.
His computer isnt bad, it runs decent in game, ive seen far worse specs then his load my pack in 5 mins, his takes an hour

 

[enterprise12]

Yeah he has on both platforms twice with no change.
Hes at a dorm, could it be the internet?
It happens every time he launches when he gets to step 7 aka last step

 

[enterprise12]

if that were true, why does this only happen on his computer and not anybody elses?

 

[enterprise12]

He has an Intel HD 5500, not the best, but i still dont see how that would be the cause

 

[enterprise12]

I ran intels driver update tool and it found no update for it

 

[enterprise12]

Update:
issue has been fixed, i manually updated his graphics driver and it fixed the problem!
thanks for the help!
