Title: [Rev4773 ] FPS dropping over time and hitting 10-15 fps at worst time.
Post by: Coldfusionstorm on 11 November 2013, 16:33:06

Revision [4773]

Basically i was playing on a map with tomreyn.

I was watching lower Left bottom corner. i could only see a bit of water.

Later in the game i was watching some palm trees.
And it did not seem to matter much obvously the fps changed a little depending on where i was. But the trend was clear the fps was declining, During this game

I started out with 180 FPS watching the entire map(aka i was a observer). when i was in the corner my FPS changed to 250 or so.

At the worst times my FPS was down to 10. and a single time below.(i think it was below 10 as i was busy in chat.).

This is the same setup I was using yesterday with Lyra. Coldfusionstorm has good hardware and a stable network link, though, so the 'n' view showed "1" for him constantly, i.e. he did not experience network or hardware / driver inflicted lag. What he did experience is decreasing graphics performance to an average of roughly 15% or 20% of his initial performance, even though he had the cameras focused on a mostly black spot of the map with no units in sight. So there should not have been much rendering work going on. He also experienced FPS drops which were severe.

My performance was ~ 55 FPS initially, dropping to ~30 FPS after the ~20 minutes we had the game running, with the lowest ever value around ~ 24 FPS. For me, the decrease was mostly constant.

Even if there is no rendering going on the computer still has to calculate for the AI and pathfinding and lots of other stuff. What hardware are you using?

my spec's are irrelevant to this situation my i was not maxed out in any sense. (i had monitoring tools on.).

Nevertheless for good measure.

AMD fx-4100 (3.6)
8 gb Ram.
AMD Gpu 7850 1gb card(so sad that i found out it only had 1 gb after i bought it).

My gpu in all test's was pretty much borred. staying in the sub 15% workload range.
cpu was some higher hitting 50% and 75% but no higher than that, and no spikes(cpu is with windows task manager tool, if you keep it open and just minimize it keeps track of cpu usage).

Is this still relevant given the 3.9.0 release?

Derek reported something like this today, but I gave no details. I vote to let it open for the moment.

What we need to know is:

a) does this only happen in network games (we must be sure)
b) if network only, does this only happen when a windows player is client only, server only or both?

With this info we could try to track this to its source.
