Soul of the ultimate nation online - Runs extremely slow with no shaders enabled

I just went back on this game and decided to install reshade, I have tried version 4.9.1, 5.0.3, 5.9.2 & 6.3.3, from the start up to the charc. selection screen, everything runs fine,
but soon as you get on the game, the game runs extremely, extremely slow, this is while no shaders are being enabled, and only few shaders were downloaded, as I just wanted to see if it will work or not, I tried to rename the d3d9.dll, it does not work, this is a very rare situation, as I don't encounter this problem.

Any help will be greatly appreciated.

I also forgot to mention this earlier:

I also tried Gshade, never used this until now, the symptoms where exactly the same.

Ok, I found out what was causing this problem, it was coming from Rivatuner, from Msi Afterburner program, if I remembered correctly, I had this problem in the past with other games, but rare.

I'll forward this to the appropriate thread on my forum, thanks.

Ok, found a temp fix for this problem:

Before loading up the game, have Msi Afterburner/Rivatuner completely turned off, load up the game, select your charc. from the charc. selection screen, the moment you go into the actual game, switch your screen to windowed mode, turn on Msi Afterburner/Rivatuner, switch to true-fullscreen mode, all set, seems to be working just fine, but just a temp fix for now, thanks.
