He was using Pseudo DxD against Vidar. True DxD G is stronger than Pseudo DxD. He can maintain Pseudo DxD for 88 minutes without consequence. He can't use True DxD G now because if he does than he would either die or close to death because the form is incomplete and unstable. He needs to awaken Great Red's power and also needs Ophis and Lilith to resonate in order for him to use True DxD G without consequence.
