My uhd 630 integrated graphics on the 8700k is achieving very low frame rates and visual problems in games such as fortnite and gta V, where it is well below acceptable. With all settings set to the lowest possible, and resolution set to 720p resolution, what should be a 60fps+ benchmark for fortnite on a uhd 630, runs well below that, at the mid to high 20's, and often dipping towards the 10's of frames. Fortnite also experiences visual problems, such as water reflections appearing as white squares, and parts of the screen going black for a second, before going to normal. These graphical issues also occur in other titles, such as gta v and the heaven benchmark, which artifacts black squares and the screen flashing green during application use. My question is whether this is normal or not for games, and if it isn't, then where to find the source behind the problem? Are there any solutions to this?
