Hi! Thank you for investigating my reply. Most hard drives even if they are 7200rpm still have a great chance of degrade in speed after years of use. This typically means the data stored on the hard drive might been fragmented. Perform a defragmentation on the drive may help a little. The worst case is that the disk itself is damaged over time and the average response time is above normal. It’s really common among all hard drives. I highly recommend you installing the game on a SSD. Speaking of the PCIe problem tho, I don’t think your pc have a PCIE 2.0 which is a pretty old standard where most graphics cards and cpu manufactured in those time period can’t really run apex at playable framerates , nor the cpu that supports motherboard with such old standards. Even if you do have a pcie 2.0 motherboard, the use of pcie3.0 lane is mostly depend on the cpu you use. You can check the motherboard and gpu connection type and speed with a tool called cpu-z. It’s a freeware by tech power ups.
