Hello guys,

I've been experiencing some issues while playing Battlefield 1 and GTA V. I usually set both games at 1080p. Battlefield 1 everything is @Low besides either FXAA or TAA. GTA V most settings are @Very High and a few others @High. What happens is whenever I am in the middle of a huge fight in Battlefield 1 my GPU usage drops to 60-75% and my FPS drops as well to around 50s. If I set 1920x1080 with TAA the drops goes to 75% usage but it means less than 60FPS while it could go higher. It also happens in servers with less players, e.g. 32p. In GTA V it happens in the middle of the city for instance, the usage drops to the 70% and the FPS to the 40's. In both games it doesn't matter if I set a lower resolution or a resolution scale or even graphics settings. GTA V will achieve almost 80FPS when not in town if I set 1600x900 but as soon as I enter the city it'll drop the usage and the FPS to the same 40's. Same for Battlefield 1. When the usage is around 90% my frames even in demanding maps such as Empire's Edge will be around 75-90 (64 players server). If I set to 1600x900 it'll drop as well. Same if I put 1080p with res. scale around 90%, what would turn into a 1728x972 resolution. It seems to me as a bottleneck. 

 

As I have explained the problem I'll also list everything I did so far in order to fix this issue:

 

Things related to the Motherboard:

• Updated the BIOS twice, with one version first (2001) and another today (3019);
• Disabled HT - nothing changed, set it on again;
• Disabled Speedstep - nothing changed, enabled back;
• Set the GPU as the primary adapter, no changes at all;
• Disabled C-state.

 

Things related to the system:

• Tried both W7 Home, W8.1 Pro and W10 Home January version and Anniversary Edition;
• Disabled Peek inside the Performance tab @ System settings;
• Disabled Virtual Memory, still the same;
• Set the Power Settings to 'High Performance';
• Unparked my cores (no performance increase or decrease);
• Uninstalled all built-in apps, disabled Windows Defender, Windows Update;
• Disabled XBOX DVR and Cortana as well.

 

Things related to Crimsons driver (Uninstalled all of them using DDU and AMD Cleanup Utility):

• Drivers used (16.7.3, 16.10.3, 16.16.11.4, 16.12.2, 17.1.1)
• Set the Wattman power limit to 50+;
• Changed the RX fan speed from Auto to 90%, nothing changed.

 

Related to the game:

• Disabled both Origin and Steam in-game/Overlay;
• In Battlefield 1 whenever I set DX12 instead of DX11 I have a stable GPU usage (around 90-99% even in lower resolutions like 1280x720) and frames ranging less, although it stutters a lot because even if I lock my framerates the CPU usage will always be around 95-100%, which causes these said stutterings - I don't know what I did a few days ago but fortunately for a few matches I played with less CPU usage and a stable GPU usage, but as I soon as I closed the game and opened it back it all started again.

 

Temps I have:

• CPU with unlocked frames goes up to 55-60ºC. If I lock it drops to 48-52ºC.
• GPU with unlocked frames goes up to 70-75ºC. If I lock it stays at 65-68ºC.

 

The programs I have are:

• Steam;
• Origin;
• Battlefield 1;
• Teamspeak;

I have no idea what is going on with this pc. What bothers me is that a GeForce 750Ti in 1600x900 or 1080p 90% resolution scale keeps the usage around 90-99% and the frames 80+ even during heavy fight with the same i3. Same for a GTX950 or a 1050. I don't know the reason behind this, if it is related to drivers or motherboard. I found a thread with not enough information but it seemed that the OP had the same Motherboard, a i5 6500 and a RX470 and had GPU usage drops as well in several games. That is why I don't know if it is the MoBo or the GPU or the PSU or anything.

Any ideas?

Thanks in advance.
