Interface-speed (menus, inventory) was horrible in my setup too. The more items in my inventory, the bigger that lag-fest nightmare became. But perhaps the next example is something to look into as a possible solution? Perhaps you could reproduce the clearly noticed speed gain as was the case in my setup. With Oblivion Stutter Remover installed, even with the suggested .ini-tweaks from Bevilex, I both have a very slow rendering map and inventory screen. But even more awful: I could easily slowly count to 3 between clicking to sell one item from inventory, before I get control back to sell the next item. But after changing the next three settings in OSR-ini resulted in instantly opening menus and selling items from inventory. (and kept my game stability): MasterbReplaceRandom = 0; was 1 bExperimentalStuff = 1; was 0 andExperimentalbReduceSleep = 1; was 0 ---> Like below:
