Issue with GT 650m (Macbook Pro)
My Macbook pro is the mid-2012 15 inch model with a 5400 RPM HDD, 4 GB RAM, i7 2.3 Ghz CPU (Turbo boost to 3.3 Ghz) and Nvidia GT 650m 512mb. I play with Vsync always off and in fullscreen mode, no other programs open (including launcher). I am using the latest version of Mavericks (10.9.2)
My issue is that the GT 650m has a stutter at any graphical setting, be very low or high settings. I have a program which allows me to choose between the integrated GPU (Intel HD 4000) and the dedicated GPU, with this I chose to use the HD 4000 to find settings that are stable for it which was medium/low - this was smooth (no stutter) and remained between 25-30 FPS.
Using the same settings and with the 650m, I get between 45-60 FPS but with a stutter. I can notch it up to high to get between 30-50 FPS as well. It's very smooth but the slight stutter gives it a laggy feel. I use atMonitor and found that the VRAM usage hovers around 75-80% and the GPU fluctuates between 40%-99% usage. I also use a program called MemoryCleaner which shows that I am using all of my 4 GB RAM.
I've read that HDD speed can have an impact on MMO games, or games that require streaming data. I plan on upgrading to 8 GB RAM (I should of done this a long time ago), could this help alleviate stutter? Would having a faster drive (7200 RPM/SSD maybe?) help? Or is the HD 4000 just better than the 650m?
Appreciate all the help you guys can give!
