This was totally fail in performance. Several players lagged so hard that they was catching up. I had 5 fps. I never had such performance drop in so small maps.

Fields Of Clusters

http://zero-k.info/Battles/Detail/458397 - this one was even more lags but this map is more friendly lag then most other maps. However in late game i had 1 fps anyway and i think pretty still to catching up.

http://zero-k.info/Battles/Detail/458392 - this one was total lag, many players lagged out and me as well (i think i started catching up)

http://zero-k.info/Battles/Detail/458387 - this one was surprisingly better in performance then other games and lower fps drop.

http://zero-k.info/Battles/Detail/458385 - this one also wasn't so laggy.

But maybe it was because there wasn't so much units in map.
I never had catching up except in 22x22 map or super speed metals or total cluster where is 15 vs 15 and game is longer then 30 min.

Can you find and comment on some large games from previous engines? My benchmark doesn't find that much difference between engines.

Yesterday i played with all medium settings. Seems that performs overall was better. I will also try with all low settings. I used default graphics settings before.
I have good gpu. Maybe my gpu is using too much my cpu resources at high settings?
There is many players who also lags out but seems they don't care about it.
I cant remember about older engines. I dont have so regular game playing and memory about because i don't make such statistics. But when things is seriously bad then i m crying in forums..
Its possible run benchmark through chobby? I could do it.
