..But horrible optimization Lag spikes galore. But a decent game. GTA V works a lot smoother on my pc...
Yeah, GTA 4 dips below 30fps constantly on my 390 on max settings with like 25 draw distance. Even on lowest settings a solid 60fps isn't really possible. Its pretty horrendous. I don't really think there is a computer that can run it properly they all seem to run it badly no matter the config. GTA 5 runs great though.
Second that! I experience lots of lag spikes, but in general 50-60 fps. Can max out settings except for shadows on my 780. GTA V is brilliantly optimized indeed Even runs at 30-35 fps on an R7 240 2GB DDR3, which is comparable to the Intel HD 530.
For me GTA IV ran way better than V. On V I had to turn graphics all the way down to get 20 fps, while IV on semi-mediun ran at 35 fps. Generally I belive that four was CPU intensive where five is more GPU intensive.
