I had download DOOM Open Beta through Steam because is free to play this weekend
I have old Ge Force GTS 450 card which is way below minimum system requoirements,but i want to test it.
I had download latest GeForce Hot Fix driver 364.96 and started game,and it was unplayable only 8 fps on lowest settings at 1280x720p
Then i had uninstall latest driver from safe mode with latest DDU Display driver uinstaller,i had download older 362.00 driver and select graphics driver,audio,and physx only and i also select clean install option, i installed driver. Now when i enter in game i have about 20-21 fps inside game meny,and 15-25 fps inside game which is unplayable.
BUT i had found this trick which works sometimes. For some reason when i start game again next time it also goes to 8 fps inside game meny. Then i am going to video option, increase resolution to 1920x1080p, and when it ask me to confirm change i select No.
After that i have double fps for some unknown reason. And i have 35-40 fps now and playable experience.
In all cases gpu core,memory and shader works at maximum frequency.
I mean wtf is happening NVIDIA? How game is working better sometimes with this trick???
Do you gimping older cards again???
I had documented Doom Open Beta gameplay on my gts 450
