Without Optifine? Even after (slightly over) 60 minutes I wasn't having any trouble. Generation kept up just fine with full-speed flying the whole time. On a 4-year old Mac laptop even, with 2 gigs assigned.
Yes, it happens with or without Optifine & Fastcraft, making no difference if they are enabled or not.
Optifine & Fastcraft allow you to freeze sooner because you can travel much faster and load/render many more chunks than Vanilla would be able to.
With or without Fastcraft and OptiFine makes no difference. That is not related to what I am reporting on here. This freezing occurs universally with nothing else required except Biomes O' Plenty and Underground Biomes Constructs mods only.
Fastcraft and OptiFine allow you to expose the problem faster because you don't have to wait forever for the chunks to load. You will be able to cover much more ground in a short time when you enable multi-core chunk loading and use the 5 chunk updates per frame setting in OptiFine.
I will re-test again with clearVarsForRecursiveGeneration on the new test46.

Sometime in the recent betas Ore Ubification has broken. A few weeks ago it was working.
Now about half of the ores in the world are un-ubified. The other half are working correctly.
It seems like Ubification is occurring or not-occurring depending on what chunk the ore is in.
In some places I see the same ore right next to itself, some ubifying, some not ubifying.
The following screenshot shows five blocks of HarvestCraft salt ore. Three of the blocks are ubified, two are un-ubified.

This was tested using InChunkGeneration=false
I wanted you to know that clearVarsForRecursiveGeneration=false seemed to cause it to freeze sooner.
