It's a remaster, so if you try to compare original game and this one on same PC, it's obvious that original game will run with a lot higher fps because it contains lower quality models and textures so it renders less details with same graphic settings and resolution. Comparing max details on relevant hardware it runs approximately the same (Reckoning on GTX 960 in HD has ~52fps, Re-reckoning on GTX 1080 in 2K has ~58fps). The original game was known for having lots of bugs, remaster have fixed some of them, but most of the rarer bugs are still there. The only help remains the same: save a lot, create new save file after each finished task and solve one task at the time (i.e. pick a task in journal, solve the problem, get reward; do not leave half-solved tasks opened for later). That way you will be able to return to unbugged state if something wrong happens in your saved game or load state before quest started if you get stucked solving it. For example: In original game some quests could be blocked if you did not pickup a quest item (e.g. from dead body) before it disappeared. In remaster you can pickup quest items even when you have full inventory, so there is no danger that the item will disappear while you go to a merchant to sell your junk. In original game some quest items could get stuck in your inventory after quest is finished if you moved them into chest while the quest was active. In remaster you cannot put any quest items into chest, so this bug does not appear anymore (but for quest, where you must collect 10 books, you CAN put them into chest because this task takes whole game to finish). To review the gameplay: It's a classic AD&D RPG (Baldur's Gate, Icewind Dale, Neverwinter Nights, etc.) with a great story, lots of side-quests and great combat system. Part of the story is the fact that at any time, you can "reset" your character and select different skills, abilities and bonuses so you are not stuck with the same character for the whole game.
