Spring framerate low [windowsXP] [0.197]

[NollyFlip]

Hi all,

I am using spring for years, but I never managed to get a good FPS ingame.

Here is my configuration :

- AMD Phenom II x6 at 2.8GHz
- 4 GB ram
- ATI R9 270
- Windows XP (yes)
- 12Mbps ADSL

I recently changed from a 8600GT to the R9 270 videocard.
But the FPS have increased only a little.
Before game start it is 220 FPS. After start 90 FPS and drop drop with time... to 3-10 FPS after 30min.

It seems not due to the video card. If I pause the game, I get back to 60 FPS.
If I underclock my video card from 1GHz to 300MHz, I have almost the same framerate.

I have no idea and it's kind of despairing. I tried many video settings. Even very low mode still lag.
Can it be the CPU ? Multithread issue ?

I watching a game replay in windowed mode (800x600) => 20FPS (during in game I was 5FPS fullscreen 1920x1080).
During this replay :
CPU is loaded 40-50% (each core, WindowsXP task manager) RAM took by spring is less than 600MB.
CPU temperature is 45°C, graphic card temperature is 37°C...

It seems video card and CPU are really few loaded.

Any idea ?

Have you tried the safemod of spring, with everything deactivated?

No, how do you activate the safe mode ?
