I believe Ogres are very different from Orcs. Orcs were born aggressive, ugly and twisted
Orcs are aggressive humanoids that raid, pillage, and battle other creatures. They have a hatred of elves and dwarves that began generations ago and they often kill them on sight.
Orcs suffer a –1 penalty to attack rolls in bright sunlight or within the radius of a daylight spell.
When they’re not actually fighting other creatures, orcs usually spend their time planning raids or practicing their fighting skills. Their language varies slightly from tribe to tribe but anyone who speaks Orc can understand them. Some orcs know Goblin or Giant as well.
While Ogres of Krynn were a beautiful race but some became twisted.
Irda
Even more lovely than elves, the original ogres were the most beautiful of all the races on Krynn, and among the most powerful sorcerers. Except in the case of injury or suicide, they had extremely long lifespans and were virtually immortal. With the passage of time, though, ogre society crumbled because of an internal division between the ogres that wanted to live in peace with the other races and those who wanted to enslave them. As punishment, the latter were turned into horrible creatures, twisted by evil.
The ogres that wanted to live in peace escaped to an isolated island north of Ansalon, and with the blessing of Paladine, became shape-shifters. They took the name of Irda to differentiate themselves from the twisted ogres. Despite their good intentions, years of isolation from the world would eventually make them a very prideful people.
Twisted Irda
The curse that turned the original ogres (Irda) into their current shape gave them a tremendous strength as well as a tendency of wild, anger-driven attitude. In the change, however, they lost most of their magical powers, concentrating only in brute strength. They live in clans, especially near mountains, and usually raid near towns to provide themselves with food and tools.
