CPU VS RAM Performance & CPU Threading Benchmarked in ARMA 3 - BETA DISCUSSION Posted April 25, 2013 · Edited April 25, 2013 by DNK Yeah, but I just don't see my pagefile being read all that much. 10 minutes of intense gameplay over 1km with a 2700m VD resulted in 434/691 reads/writes, for a total of 13MB read and 723MB written (obv, a lot is being written, likely at game start, though I had other programs running in the background, including Firefox, so it could've been W7 moving their RAM files onto the pagefile). Immediately after stopping play and resuming the other programs, I got a ton of new reads (10k+ for over 200MB in 4min), which sort of supports my idea that a lot of those writes were moving lower-priority stuff out of the way, not moving game-related files around during play. By comparison, reading of the "anims_f_data.pbo" was at 1600 with 44MB read; "sounds_f.pbo_" had 1370 reads for 47MB; "map_stratis.pbo" was 1333 for 27MB. The pagefile just isn't being read that much compared to the disk, and I severely doubt the game or Windows is placing such extremely highly used data like that in the FSM on the pagefile and reading it from there often. If it was, it would be reading it every frame, perhaps multiple times, which would have over 10,000 reads in 10min. Same goes for textures/models being referenced every frame or every few seconds. I don't know how much time needs to elapse between when they are last used and W7 shoves them off to the pagefile, but it can't account for frame-by-frame low performance when your view isn't changing that much. That's more likely the latency/bandwidth between main RAM and the GPU or CPU. Additionally, the game is only using about 1.4GB of 2.5 available, so the Prius is hardly full even with a 2GB limit.
