Prior to the Ryzen launch, we discovered an issue with GTA V testing that would cause high-speed CPUs of a particular variety to stutter when achieving high framerates. Our first video didn’t conclude with a root cause, but we now believe the game is running into engine constraints – present on other RAGE games – that trigger choppy behavior on those CPUs. Originally, we only saw this on the best i5s – older gen i5 CPUs were not affected, as they were not fast enough to exceed the framerate limiter in GTA V (~187FPS, or thereabouts), and so never encountered the stutters. The newest i5 CPUs, like the 7600K and 6600K, would post high framerates, but lose consistency in frametimes. As an end user, the solution would be (interestingly) to increase your graphics quality, resolution, or otherwise bring FPS to around the 120-165 mark.

Then Ryzen came out, and then Ryzen 5 came out. With R5, we encountered a few stutters in GTA V when SMT was enabled and when the CPU was operating under conditions permitting the CPU to achieve the same high framerates as Intel Core i5-7600K CPUs. To better illustrate, we can actually turn down graphics settings to a point of forcing framerates to the max on 4C/8T R5 CPUs, relinquishing some of the performance constraint, and then encounter hard stuttering. In short: A higher framerate overall would result in a much worse experience for the player, both on i5 and R5 CPUs. The 4C/8T R5 CPUs exhibited this same stutter performance (as i5 CPUs) most heavily when SMT was disabled, at which point we spit out a graph like this:


Rockstar games recently indicated through support channels that it has “received reports of lower framerate in GTA V and GTA Online after Title Update 1.28 on PC,” further stating that the company is investigating said reports.

A week of benchmarking behind us, we've now tested most major aspects of Rockstar's new GTA V PC release. We've elected to adopt the game into our test methodology for future component reviews, given its wide performance demands and load balancing between the CPU and GPU. This final GTA V benchmark looks at CPU bottlenecking at various resolutions and settings; we pit the 3570K, 4790K, FX-8320E, FX-8370E, FX-9690, G3258, and Athlon 760K against one another.

The selection casts a wide net for core count and price points, hopefully illustrating where CPU bottlenecks may appear in playing GTA V.

GTA V shipped alongside an onslaught of graphics settings – none of which offer tool-tips – that can vastly control the fluidity of gameplay. In our recent and comprehensive GTA V benchmark, we tested multiple video cards for FPS at simple “max” and “high” settings, fluctuating resolution between 1080, 1440, and 4K along the way. That content now behind us, we took the opportunity to objectively benchmark various graphics settings for performance differences, then took a few screenshots for comparison of those settings.

This GTA V optimization guide assists in choosing the best graphics settings for frame-limited video cards, explaining the options along the way.
