On my current PC that I built a few months ago I'm having a strange problem with the graphics card. I'm not a huge gamer anymore, but I have a few shooters and racing games installed that I play off and on.
My graphics card is an MSI GTX 750 Ti. The core clock speed is 1050 MHz and it a boost clock of 1163 MHz. With MSI Afterburner I overclocked the GPU 187 MHz to bring the boost clock to 1350 MHz. Memory speed is untouched as well as voltage.
All my games play fine except one. Temps are never higher than around 70. The card runs stable and I've experienced no crashing or freezing in games unless I try to push the GPU above 1400 MHz. The problem is with the racing game Split Second. This is one of my favorite games of all time and even though I don't game that much anymore, when I want to play a racing game, it's usually the one I go to first.
When I built this system back in late September, the game worked fine the few times I played it. Yesterday is when the problem started. I loaded up the game and the core clock of the card won't go above 405 MHz once the game loads. On the Title/Options screens it will go to 1050 MHz, but once a race starts, it won't go past 405 MHz resulting in a slideshow. Another strange thing is that the OSD for Afterburner/Riva Tuner works fine in every other game I own and on the title/options screens for Split Second, but once the main race loads, the OSD disappears. The way I know it's not going past 405 MHz is by looking at the Hardware Monitor graph inside Afterburner after alt-tabbing out of the game or shutting it down.
Even stranger is that even after closing Split Second, the card won't go above 405 MHz period. Not in any other games, Passmark tests, nothing. The only way to make it ramp back up like it should is to restart the computer. Then of course after loading Split Second again, it locks at 405.
Any idea what the problem is? I've tried every driver version from the time when I first got the card and it worked properly, up to the most recent one using Display Driver Uninstaller between each. Tried running the card at stock speeds too. I have no idea what the problem is. Nothing has changed in the MOBO BIOS since the card worked properly with Split Second either. I'm at a loss here. Had the game always been this way, I'd chalk it up to the game itself, but as I've said, it worked fine the half a dozen times I played it after this build and it only recently started doing this.
One more thing, I also changed the "Power Management Mode" option for Split Second inside the nVidia control panel from it's default "adaptive" to "prefer maximum performance" to no avail. Even setting the option globally to maximum performance has no effect.
The rest of my system specs are below:
Skylake 6600K @ 4.5GHz
16GB Corsair Vengance DDR4 2400MHz
ASUS Z170 Plus MOBO
Silverstone 450W SFX PSU
Windows 10 x64
Thanks for any ideas on this. After thinking for a second (no pun intended), it's almost as if the card/drivers aren't seeing the main race portion of the game as a 3D application and not boosting the core speed for some reason. As far as it locking to 405 MHz after the game exits, I really don't know.
