Disappointing performance, bk on Mac Pro (6 core xeon)

Postby x420pikachus69x » 05 May 2018, 08:54

Hi I'm playing coh bk on 5,1 Mac Pro 3.33ghz 6 core xeon, 980ti, 16gb ram, 144hz monitor. Vanilla coh runs fine 144fps. Bk mod wont even run at 144hz, i set refresh rate to 120 otherwise every few minutes it will go "out of range", impossible to play; tho its no problem because 120hz is plenty. On small maps I get 80-120fps, on medium-large maps i get 40-80fps, plenty playable but annoying at times. I believe I have the recommended gfx settings.
Launch tag looks like

Code: Select all

-mod Blitzkrieg -dev -nomovies -window -fullwindow -forceactive -lockMouse -refresh 120

If I dont use -window -fullwindow i get much lower fps. I also use razer cortex, another sometimes annoying but useful program that frees up ram and windows services and stuff; increasing fps significantly. Any idea? It's a 10 year old CPU, but its a 10 year old game, and it was the pretty much fastest CPU when this game released. cohv runs perfectly, does the bk ai eat up a ton of cpu? I haven't played online yet (cant find a pvp game).

Obviously your PC specs are more than enough to run the game but BK mod (and sometimes even vCoH) lags because of the game engine optimization. Relic never really properly optimized the game. Also CoH can only use one core of your processor so I guess it would be better to have a single-core processor with huge clocking than multiple-core processor with lower clocking per core.

The lags are usually more noticeable when you play vs AI - the CPU needs to calculate movement, hit chances, penetration chances, damage rolls etc. per every shot fired and AI (since it "cheats" on higher difficulties and receives extra resources) usually keeps spawning tons of units (more than real players do) which only means more calculations and more work for the CPU. The problem seems more obvious when playing BK mod because BK mod allows players to build more units - recommended match settings basically means "no pop limit" while vCoH was usually played with the "capture sectors to increases pop limit" system. And since AI gets more resources, it can afford to use up more of the "unlimited" pop cap.

Anyway - try to set the everything in the Graphic options to "High" instead of "Ultra". "Ultra" settings use DX10 and the game doesn't know properly how to work with DX10 (again, an unfinished thing in the game engine) - the visual difference is hardly noticeable anyway.
Also try to avoid playing maps with the "rainy weather" settings on - it only creates more work for the CPU.
I also think that someone said that if you set in your nVidia driver for CoH the "maximum pre-rendered frames" to "1" it also helps, but I am not 100% sure about this.

If that's a MacPro, are you using MacOS or did you put Windwos on it?
Mac doesn't play nice with the engine afaik;
Also, the Xeon processors are not that fast and BK has much higher requirements than vanilla.

Ideal specs for BK mod are i7 7700K OC to 5.0 GHz + GTX 750 Ti (or weaker)

I'm playing on Windows, however vcoh runs fine in vmware fusion, bk does not.
