After buying my Alienware PC over a year ago, I was quite confident that it was a beast of a machine. I'm running a 3,7GHz Intel i7-4820, 16 GB RAM, 3TB HDD, and a GTX 690 (a 4GB dual-GPU card). I was able to play Skyrim on "ultra" settings and I never noticed any lag in the game whatsoever. Although, there seemed to be some physics issues, though I suspect that was an issue with the game, not my hardware. However, once I got GTAV for the PC and letting Geforce Experience optimize the game for me, I noticed some lag. I'm not sure if it's because my hardware can't handle some of the settings or if it's because of the game. I still suspect that both may be the case, after all GTAV just came out and although it's been optimized for multiple kinds of hardware, there is likely some bugs that haven't been worked out yet.
Because of this issue, I've done a lot of "research" ("Googling") on how to optimize my PC for the game. Ultimately, I think I found a good solution just by changing some simple settings. I've know for a while now that Geforce Experience can "optimize" games for you based on your hardware. Since I've had this PC, I've let it do that and it seems to often increase settings from their game defaults. I've also learned about settings in the Nvidia Control Panel.
I've been aware of PC and GPU over-clocking, but I haven't actually done that nor do I think I've used any kind of over-clocked hardware. I think it's a bit too risky and seems like a bit of a task with a lot of trial and error. I know there are multiple tools and guides out there to help you do this. So, I wonder if any of you have done any over-clocking? If so, please share your experience.
I'm also aware of different tools that can help you optimize game settings. Nvidia Inspector is one of these tools that I found. It's much like GPU-Z, which helps you monitor your hardware and has game profiles that can be set. Do you have any experience with these or similar tools? Let me know.
Feel free to also share your PC specs, if you wish.
